It's clean, as I only assembled the mat and arranged the tiles once after opening the package. It can be stored compactly and is convenient to carry. There is no box, so I will wrap it in bubble wrap for shipping. Below is information from the Amazon listing where I purchased it: A standard set of mahjong tiles and a dedicated mat. The mat uses SBR, the same material as wetsuits. It is resistant to water and dirt. By removing two frames, the framed mat can be rolled up and stored in the carrying bag. The frame has pockets for scoring sticks, so you can see each player's score at a glance. It is lighter than a regular rubber mat, and the rolled shape (unevenness) is less noticeable than on a rubber mat, and it recovers quickly. The tiles use authentic urea resin. The back of the tiles is yellow. In addition to scoring sticks, a parent marker, and dice, a beginner's guide book is included so that even beginners can enjoy the mahjong game with peace of mind. A carrying bag is included to store both the mat and the tiles. You can enjoy mahjong right away, and it doesn't take up much space for storage and carrying. The mat's outer dimensions are approximately 69cm per side. Photos 3, 4, and 5 are from the Amazon listing.
