Thank you for looking! I've used this for a little while, but I don't play with it much anymore, so I'm selling it. ・I believe it was the Dream Set Basic 578-piece product, but I threw away the instructions, so I'm not sure. I think there are about that many pieces, so please check the photos for the volume. ・The child may have lost some pieces, but please understand. ・The included poster and case are not included. Only the blocks will be shipped. ・Original price was about 15,000 yen. ※No pets, no smokers. I plan to ship via Rakuraku Mercari. Thank you!
