Using this clutch wallet is a breeze. You can use the clear - view ID window to quickly show your ID when needed. Slide your credit cards into the 8 slots and bills into the dedicated pocket. For smaller items like receipts, use the slip - in and open pockets. When you want to carry it on your shoulder, attach the adjustable shoulder strap. If you prefer to hold it in your hand, use the wrist strap. To keep it in good condition, avoid placing it in very wet or dirty environments. If it gets dirty, gently wipe it with a soft, damp cloth. Don't use harsh chemicals as they may damage the soft canvas material. Also, be careful when zipping and unzipping to prevent the zippers from getting stuck.
