Soft, white resin joint mats. The tile surface is 30cm square, excluding the connecting parts, and about 8mm thick. I bought these and tried to lay them down, but they didn't fit the size of my bathroom, so they've been stored almost unused. Perfect for bathrooms and wet areas. I'm also selling green ones at the same time. If you'd like to change 12 of these to green, please consult with me before purchasing. Thank you for looking.
