This item is an order for Namer-sama. This is a mousepad made from calfskin. The leather used is combination-tanned, which is more water-resistant than vegetable-tanned leather and easier to care for. Thick leather was used to maintain a smooth texture and softness. In addition, the uneven grain (wrinkles unique to leather) around the back was intentionally used to create a genuine leather appearance that cannot be found in synthetic leather. The size is W220mm H170mm D7mm. (The inside of the step is W200mm H150mm.) The weight is approximately 179g, which makes it feel somewhat heavy for a mousepad. The leather, stitching, and edge are finished in black. Thank you.
