Math blocks used in the first grade of elementary school. I am selling these as I no longer need them due to moving up a grade. There are some minor scratches, but they haven't been used for a long time, so I think they can still be used. *There is no name written on them, but I had put name stickers on them, so there are some places where the stickers were peeled off. I wiped them with alcohol wipes, but there are some stains that won't come off. Please check the photos from the third image onwards (as in the third image, most of the 10 picture cards have sticker residue). Please check the photos and consider purchasing only if you understand that these are used items stored by a private individual. [Product Description] Set of blocks with different colors on both sides ⚫︎The colors on both sides are different.
