A colorful educational set for fun learning of arithmetic and time. - Product Name: Sansu Box (Arithmetic Box) - Contents: Calculation tools, clock, colorful building blocks, animal-shaped puzzles - Educational Goals: Arithmetic, time learning, color recognition - Accessories: Money pieces, calculation cards, clock hands - Design: A box with colorful illustrations for children This is an arithmetic set used by elementary school students in grades 1-2. Name stickers were basically applied for use. Although all the stickers have been removed, adhesive residue remains, and some of the paper cards are torn. It probably won't be noticeable if you apply name stickers on top. The names were directly written on the four dice, so they have been erased with a permanent marker. The "addition cards (2)" and "subtraction cards (2)" are missing from the calculation cards. I believe there are no other missing items, but I apologize if I have overlooked anything. The calculation cards are not torn, but they show signs of use. Overall, there are signs of use and some stains that cannot be removed. *Please read the self-introduction.
