What a perfect mat to take on vacation to the beach, or even the local coffee shop. Bright crisp colors and beautiful finishes make this mat a must have! Instructions in the corners are a bonus. The surface is smooth and the tiles move easily. 31.5 x 31.5 is the measurement. There is an adequate application of rubber silicon on the back to prevent creasing. Mats are normally sent folded in a polybag. I’m happy to mail them rolled in a box if you prefer for an additional $4.00 mailing costs.
