Taiwan-made drink holder, the BAG TO GO eco-friendly beverage bag. Taiwanese goods ★ Lightweight and foldable for portability! ★ Holds a 500ml drink securely! I bought several as souvenirs, but I have some left over, so I'm selling them new, unopened, and unused. However, please purchase only if you understand that they have been stored at home. m(_ _)m #drinkholder #500mlpetbottle #ecofriendlybeveragebag
