Removing glitter form bagWatch
I don’t think anyone would actually notice.
It depends on how the glitter is attached. If it's a superficial layer on top of the fabric, you could use sellotape or a lint roller to pull as much off as possible. If the glitter is woven into the fabric, then there is no way to remove it.
It probaly got damaged by a kid or something and now the sellers are just trying their luck to make a quick buck on it hoping you won't kick up a fuss.
