Singapore’s National Day season is always a good excuse to get out, explore the city and enjoy a little something extra. This year, KOI Thé and MARVIS are giving bubble tea fans another reason to make a stop at selected outlets with a limited-time National Day promotion that combines a refreshing drink with a complimentary premium toothpaste.

The KOI Thé x MARVIS National Day Special is running from 17 to 30 August 2026, with the promotion taking place in two different locations during separate periods. Customers who purchase a Large Green Milk Tea with Aloe Vera at the participating KOI outlets can receive a complimentary MARVIS redemption card, which can then be used to collect a 10ml MARVIS toothpaste at the designated Watsons pop-up location.

For anyone who already enjoys KOI Thé, this is quite an interesting deal because the purchase comes with something extra that can actually be useful. Instead of simply getting a drink and heading home, customers have the opportunity to pick up a complimentary MARVIS product as part of this special collaboration.

A KOI Thé Drink Comes with a MARVIS Treat

The main attraction of this National Day promotion is fairly straightforward. Customers need to purchase a Large Green Milk Tea with Aloe Vera at one of the participating KOI outlets during the relevant promotional period.

After making the qualifying purchase, a complimentary redemption card will be provided. That card is important because it is what customers need to present at the designated MARVIS Watsons Pop-Up to claim the free toothpaste.

The complimentary product is a 10ml MARVIS toothpaste, with the flavour distributed at random. This means customers may not be able to choose their preferred flavour, but it also makes the redemption a little more interesting because the toothpaste received will be a surprise.

For those who have been curious about trying MARVIS but have not wanted to commit to a full-sized tube, a complimentary 10ml version is also a convenient way to sample the brand.

Two Locations, Two Different Promotion Periods

One thing to watch carefully is that the two participating KOI locations do not run the promotion at the same time. The dates are divided between Takashimaya and Bugis+.

From 17 to 23 August 2026, the promotion is available at the participating KOI Thé Takashimaya outlet. Customers who qualify during this period can redeem their MARVIS toothpaste at the MARVIS Watsons Ngee Ann City Pop-Up at #B2-06.

The second period runs from 24 to 30 August 2026 at the participating KOI Thé Bugis+ outlet. Customers making the qualifying purchase during these dates can head to the MARVIS Watsons Bugis Junction Pop-Up at #02-29 to redeem their complimentary toothpaste.

This arrangement means shoppers should pay attention to both the date and location before making a trip. Someone heading to the wrong pop-up on the wrong date may not be able to redeem the gift, so keeping the promotion schedule handy is worthwhile.

There Is Also a MARVIS and KOI Giveaway

The free toothpaste is not the only reason to take notice of this collaboration. KOI Thé and MARVIS are also running a giveaway for those who want to take their National Day celebration a little further.

The giveaway prize bundle includes a MARVIS Sticker Sheet, one month worth of KOI vouchers, a Classic Strong Mint Toothpaste and a Whitening Toothpaste. For regular KOI customers, the month-long KOI vouchers could make this giveaway particularly appealing because the potential prize goes beyond just receiving another promotional sample.

Entering the giveaway requires a few simple social media steps.

First, participants need to like the giveaway post and follow both @koithesingapore and @marvissingapore on social media. Next, they need to take a photo of the promotional Green Milk Tea with Aloe Vera and tag @koithesingapore. Finally, participants should comment with their favourite MARVIS toothpaste flavour.

It is worth checking the original giveaway post for the latest instructions and any additional terms before entering, particularly because social media promotions can have specific eligibility and closing requirements.

Why This Deal Is Worth Checking Out

There are plenty of National Day promotions taking place around Singapore, so why should this one make the list?

For starters, the promotion is easy to understand. Customers are already buying a drink they may have wanted anyway, and the qualifying purchase gives them an opportunity to receive a complimentary MARVIS toothpaste. It is a simple value-added deal rather than a complicated discount structure that requires several purchases or a lengthy redemption process.

The collaboration itself is another attraction. KOI Thé is well known for its range of tea and milk tea drinks, while MARVIS has built a reputation around its distinctive premium toothpaste range. Putting the two brands together creates a rather unexpected National Day pairing.

There is also a practical benefit. A 10ml toothpaste may be small, but it can be useful for travelling, keeping in a work bag or simply trying a new product before buying a larger size. Since the flavours are distributed randomly, customers may also discover a MARVIS variety they would not normally choose.

The giveaway provides another reason to participate. Even if someone does not win, the entry process is relatively straightforward for those who are already purchasing the promotional drink and using social media.

A Good Excuse for a National Day Out

This promotion could easily fit into a shopping trip around Orchard or Bugis. Customers visiting Takashimaya between 17 and 23 August can combine their KOI Thé purchase with a visit to the MARVIS Watsons Ngee Ann City Pop-Up. From 24 to 30 August, those around Bugis can make use of the Bugis+ promotion period and then head to the MARVIS Watsons Bugis Junction Pop-Up for the redemption.

That makes the deal particularly convenient for shoppers who are already planning to be in these areas. Rather than making a separate trip solely for a small promotional item, customers can incorporate the redemption into their usual shopping, dining or National Day activities.

However, there are a few things worth remembering. The promotion is only available at the stated participating locations and during the specified dates. The complimentary toothpaste is also subject to availability, so customers should not leave the purchase and redemption until the very last minute if receiving the MARVIS gift is the main reason for visiting.

Most importantly, customers should keep the redemption card after purchasing the qualifying drink. The card needs to be flashed at the designated MARVIS Watsons Pop-Up to claim the complimentary toothpaste.

Final Thoughts

The KOI Thé x MARVIS National Day Special is a nice little promotion for anyone who enjoys bubble tea and likes discovering premium personal-care products. A Large Green Milk Tea with Aloe Vera provides the refreshing part of the deal, while the complimentary 10ml MARVIS toothpaste adds something different to the experience.

The additional giveaway makes the collaboration even more interesting, especially with a month of KOI vouchers and two MARVIS toothpaste products included in the prize bundle.

With the promotion split between Takashimaya and Bugis+, planning ahead is the best way to avoid missing the correct redemption location. The offer is also limited by availability, so interested customers may want to visit earlier rather than assuming the free toothpaste will still be available at the end of the promotion.

For those looking for something different to enjoy during Singapore’s National Day period, this KOI Thé and MARVIS collaboration offers a simple reason to grab a favourite drink, explore the pop-up and potentially walk away with a complimentary toothpaste. Add the giveaway into the mix, and there is even more reason to give this limited-time promotion a try.
