This is one bottle of black Glass Deco from Yamato Co., Ltd., also usable for outlining. I bought a set of two on Amazon last August, and this is the extra one. The packaging seems to have changed, but it's from the same company. It's been left out, so it has some dust on it. If you don't mind the dirt on the outer bag, please consider purchasing it. m(_ _)m I will dispose of it if it doesn't sell this month.
