Tired of buying separate travel-sized shampoo bottles? The Carry On is a smart solution. It includes a mini bottle that attaches to your regular shampoo bottle, making it easy to take with you on trips. You can refill it whenever needed, saving you from buying extra bottles for travel.

The Carry On, winner of this year’s Asia Design Prize, is a big 1-liter shampoo bottle with a built-in handle. When you buy it, you also get a smaller bottle that fits neatly into the handle. The smaller bottle, 50ml, is perfect for your toiletry kit on a week-long trip. You can use your favorite shampoo instead of the ones from your hotel.

Carry On has some award-worthy features. While getting a free smaller bottle with a larger one isn’t new, Carry On’s design is genius. It cleverly fits the small bottle into the space created by the larger bottle’s handle, making use of what would otherwise be wasted space. Plus, the mini bottle’s rounded design resembles a bar of soap, creating an immediate toiletry association. Pretty clever, right?
