This is a BRUNO multi-slate. It has a solid thickness and a substantial feel. I purchased four, and these two were hardly used, stored in the cupboard. Chalk and original picks are also included. 39cm x 13cm Non-slip backing Due to the natural material, there are individual differences in edge chipping and surface irregularities. It's a convenient long size. Because it's slim, it's perfect as an accent on the table. Please arrange sushi, appetizers, etc., in a stylish way. Please refrain from purchasing if you are concerned about minor details, as it has been stored at home.
