This is dental floss that came with an electric toothbrush I subscribed to about six months ago. I forgot to cancel the subscription, so I have a lot of it. I don't use floss, so I'm selling it. 1 bag: 30 pieces This is a set of 6 bags, but I have 8 bags in total. Additional bags can be added for 100 yen each. (Minimum 6 sets) I am not considering lowering the price, so I will only answer inquiries about the quantity.
