I purchased this previously and have been storing it at home. I'm not certain if it was used, but it weighed 501g including the packaging, so it seems like almost all of it remains. I hope someone who can use it will take it. - Contents: 500g - Product Name: Gofun (Oyster Shell White Pigment) ★Bulk purchase welcome We welcome bulk purchases with other pigments and art supplies.
