Special gradient bottle commemorating the 15th anniversary. This is a limited edition item available only now. The refreshing color makes it easy to see how much floss is left, which is also recommended. It's also cute to combine with the regular colors♪ This is a brand new, unopened item. As a bonus, I will include a regular color 250m bottle of Floor Floss. It has been opened and used a little, but I believe it has about 80% remaining. It was stored in a drawer, and the thread dispensing opening and cutter are the old type, but the floss itself is the same as the current product. There are some minor scratches on the case, so please consider this as a bonus. It's a daily consumable item, so you can use it generously(^^)
