I bought this thinking it would be good for my child who loves stones, but they showed no interest at all. They touched it for a few minutes after opening it, and I've been storing it since then, with no sign of them wanting to play with it. I'm selling it because it would be better for someone who is interested in it. The item was imported from overseas, so there were dents on the outside of the box and dirt inside the box from the beginning. I didn't check the dirt on the bags carefully, so I'm not sure if it was there from the start or if it got dirty later. Since it was only used for a few minutes, I think it was probably there from the beginning, but there's also a possibility it got dirty during that time. Please check the condition of the dirt before purchasing. The blocks themselves are clean. You can stack them, use them for pretend play, or play with them however you like (^^) They are very light. There are 10 pieces in total: 4 large, 4 medium, and 2 small. #HIMIKUBLOCKS #HimikuBlocks #EducationalToy #BuildingBlocks #Blocks #BlockLover #PretendPlay #Boys #Girls #NurserySchool #Kindergarten
