3 Tips for Storing a Mousepad Flat
Store your mousepad flat, not rolled Warping happens when you roll a soft mousepad tightly for a long time or leave it on a hot surface. Stack it under a book or in a shallow drawer to keep it flat.
Cover it with a light cloth or sleeve Dust is the main concern, so a thin cloth like an old t-shirt or a cheap plastic sleeve works fine. Avoid vacuum-sealing it, as that is overkill.
Skip specialty cases You do not need a special box or case. The cardboard tube it came in works as a sleeve if you must roll it, but flat storage is better.
