Easy Writing Board [M Size] Width 560 x Depth 450 x Thickness 14mm, When in use: Width 560 x Depth 450 x Height 91mm Weight: Approximately 3 kg Purchased from an authorized Rakuten store around April of this year for about 24,000 yen. I bought it for my child who started elementary school, but they don't study at home much because they do their homework and study at cram school, so it hasn't been used at all. I think their posture improved when they used it. It has been stored upright on the floor. The surroundings are made of rubber, so there are some original dents. Please check the images. There are no noticeable stains or scratches, but please refrain from purchasing if you are sensitive to things like packaging, dust, or hair. There is no original box, so it will be packed with bubble wrap and cardboard.
