This is a B5 tank bag made by TANAX. Model number: MFK-027 Color: Black. Convenient with mesh pocket and side pockets. It can be fixed to the tank with 6 magnets and won't slip. I tried it once for a motorcycle touring trip, but it didn't quite fit, so I've been storing it at home. I'm selling it because I don't plan to use it. First come, first served. Thank you.
