Using these Notion Nooks is a breeze. Just open the magnet - locked lid, and you can start filling it with your stitch stoppers, tools, and trinkets. The transparent flaps make it easy to see what's inside without rummaging around. When you're done crafting, simply close the lid, and the magnets will keep it shut. As for maintenance, you can use a damp cloth to wipe the outside of the case if it gets dirty. Avoid using harsh chemicals as they might damage the plastic. Also, don't overfill the case as it could affect the locking mechanism.
