LEGO-compatible blocks. I purchased these as a souvenir during an overseas trip, but I haven't used them, so I'm selling them. This is a new, unopened product, but it has been stored at home for a long time, so there may be some warping of the box. Please note that this is an inexpensive item, and will be delivered with simple packaging. Thank you for your understanding. - Brand: sembo block - Product Name: Mini Workshop Thank you for looking.
