Purchased at Yuzawaya store. Stored at home for 1-2 years. There are no pets or smokers, but please refrain from purchasing if you are sensitive to household odors. It was on sale, so I stocked up, but I don't have time to make anything, so I'm selling it. Please read my profile. This item is available for immediate purchase! I am also selling other craft kits that I have stocked up on. Shipping will be by Yu-packet Post Mini or Yu-packet Post, with anonymous delivery.
