It's very effective for learning nouns (names of things). 【Classification by Category】 The basic principle is to group flashcards into sets by the same category. For example, in the "Animals" category, don't mix in cards from other categories. 【Easy on the Eyes】 The advantage of paper flashcards is that they are "easy on the eyes." They are perfect for parents who think that apps on tablets put a strain on toddlers' eyes. ... Some of the readings have been written in with a marker, but they have hardly been used and have been stored away. There is no box case. I bought it on Amazon for about 3000 yen, but I bought other teaching materials, so I won't be using these, and I'm putting them up for sale. Please understand that I cannot be held responsible for any bending during shipping. Please refrain from price reductions.
