Brown nanoblocks. 18g in various shapes. Stored at home and used. Nanoblocks are very small blocks, so they are not suitable for young children to play with. Please be careful not to mistake them for other blocks. Photo 2 shows everything included. Photos 3-6 are enlarged photos of Photo 2. They will be shipped together as shown in Photo 7. Please check the condition in the photos. These are items used by children. Also, I have removed any dirty blocks as much as possible, but there are some blocks that have discoloration. Please take a good look at the photos, and if you have any concerns, please refrain from purchasing. I'm not sure if it's due to differences in the lot or product, or differences in storage, but if you look closely, there are blocks with different shades of brown. This is noticeable if you look closely at the photos. Please consider purchasing only if you understand that these are used items. Shipping will be via "Yu-Packet Post Mini." Photo 7 will be wrapped in bubble wrap and shipped in a dedicated envelope. Thank you for viewing. Seller's internal number → Nanoblock Brown 001
