I purchased this at Daiso. I bought this diorama sand for handicrafts, but I didn't use it, so I'm selling it. I no longer have the packaging, but the bag is unopened. Excluding the weight of the bag, I think there's about 100g. I bought it several years ago, so the amount may be different from what's available now. For those who understand that this has been stored at home. Recycled materials may be used for packaging. Please read my profile before purchasing m(__)m
