the tube is about the size of a regular glue stick (but it's liquid!). if there's interest, i can provide pictures and more details.
i haven't used it myself, so i can't answer any questions about how good the product is.. but it's the exact same kind they sell in japan, so i think it's okay (:.
i'd charge $3.50 each + $1 shipping (amounts are in USD). i can get a hold of a lot.. like.. up to 20 pieces :P.
