KUMON Number Board 100 Educational Toy I purchased this last year for my preschooler who didn't understand numbers above 20, and we used it for about six months. By using this to count and arrange the numbers, and by playing with it like Othello, my child was able to understand numbers up to 100 all at once! I think it was really effective for my child (・ω・) We haven't used it since then, and it's been stored away. I hope to pass it on to someone who needs it (*・ω・*) * Purchase date: Last year * Usage period: About six months * Box, instructions, number magnets, and board are all included. * The instruction manual and bag are 【unopened】 and unused. When listing, I wiped the magnet parts, the transparent board for arranging the numbers, and the board itself with disinfectant wipes. ★ There is some damage to the opening of the box. ★ There are some scratches and discoloration on the board, the board, and the back of the magnets. Please be sure to check the photos. ※ Please be especially careful of accidental ingestion in households with small children or pets. This is a used item that has been stored at home by a private seller. There may be small scratches that cannot be fully captured in the photos, but please understand this before purchasing. Shipping is planned using Rakuraku Mercari. The board will be wrapped in bubble wrap, and the box will be wrapped in a plastic bag to prevent it from getting wet. It will be shipped in a bag or box of the appropriate size. Also, depending on the packing size and shipping circumstances, Rakuraku Mercari may occasionally be changed to Yu-Yu Mercari. I will notify you via message if there is a change. If you have no particular preference, I will ship it without waiting for a reply in order to get it to you as quickly as possible. If you cannot accept changes, please let me know in advance via message. ■ Magnet Number Board 100 ■ Target age: 3 years old and up ■ Main body size: Pieces: Diameter 2.6cm x D0.6cm, Board (when spread out): W429.9cm x H39.9cm x D0.2cm ■ Package size: W32.7 x H23.6 x D3.0cm ■ Total weight: Approximately 871g ■ Set contents: Pieces: 100, Board: 1, Storage bag: 1, Instruction manual: 1
