To use these notion nooks, simply open the magnet - locked lid and put your stitch stoppers, tools, and trinkets inside. You can easily see what's inside through the transparent flaps. When you're ready to craft, just slip the nook into your project bag. To keep them in good condition, avoid dropping them from high places as they're hard plastic but can still crack. Clean them with a soft, damp cloth if they get dirty. Don't use harsh chemicals as they might damage the plastic or the magnets.
