I made a whiteboard by laminating design paper. You can write on it with a whiteboard marker and erase it with a tissue, making it convenient. We use it at home too. How about sticking it on your refrigerator for shopping lists or messages from your children? ^_^ *Size* 21cm x 15cm It's the size of an A5 notebook. It's also cute to put it in your notebook. It's thin because it's laminated with one sheet. This is a handmade item made with care, one by one. Please understand any slight distortions in the lamination before purchasing.
