Using this wallet is easy. Just unzip it to access your cards and ID. You can put your credit cards, membership cards in the four card slots and your ID in the clear slot. When you're done, zip it up to keep your items safe. As for maintenance, avoid getting it wet as it might damage the glitter and the vegan leather. Wipe it gently with a dry cloth if it gets dirty. Also, be careful not to overstuff the wallet as it may cause the zipper to malfunction. This is an officially licensed Disney product, so take good care of it to enjoy it for a long time.
