This item was purchased new on Mercari for 1250 yen. I have only used it from 1 to 10. There may be some signs of use, but from 11 onwards, it is brand new and unused. The front of the dots cards from 1 to 50 have red dots. The back has the numbers 1 to 50 written on them. There are a total of 50 cards + a cover page, all of which are flashcards. By showing the dots cards, you can stimulate the calculation ability of the right brain. A5 size. Not rounded corners. Thickness is approximately 0.25mm. *Home printed. Please understand in advance that this is a handmade item. *Discounts are available for combined shipping with other cards I have listed. #Shichida #Kumon #Flashcards #Right Brain Category...Flashcards
