This is a collaboration muffler between any FAM and Shirotan. I received it as a gift, but I am selling it because I already have a similar muffler. The following is quoted from the official website: ↓ ↓ ↓ Shirotan wearing a crown on a fluffy muffler! ● Shirotan celebrates its 25th anniversary this year. ● Keeps you warm from your neck with its fluffy material! ● Perfect for gifts♪ A collaboration item between Shirotan, celebrating its 25th anniversary this year, and any FAM is here! It's a very cute pochette♪ Shirotan wearing a crown is holding a star motif and a star wand. It's sure to be useful as a cold-weather item for long outings on cold days, during travel, or when riding a bicycle. It's also a perfect gift item for this season. Why not go out with Shirotan this winter? Size: Total Length x Width 74.0 x 9.0
