The color of the product is slightly different, because this is our DIY handmade (heat transfer) 2. When I received the package, there was a little smell when I opened it, but it was non-toxic. It will be better to put it in a ventilated place after a few days 3. Warning: All products are measured manually, please allow 1-2 deviations. We also customize mouse pad designs.
