yee si by YEE SI is YEE SI’s latest sister line. The flipped opening of the Click Tote makes it become a fancy design bag among all. It has multiple intellectual property protections. When you open the bag and your hand leaves the top of the bag, it is designed to close automatically, preventing items from being lost and providing you with more fun and security. Inspired by kids’ origami games. The leather tote is opened and closed by folding.
