This is a tank bag (MFK-258) from Tanax. It's a tank bag with a clear window and is easy to use with straps. - Brand: Tanax - Model Name: MFK-258 - Accessories: Straps - Design: With a clear window I've only used it once for a touring trip. It's good for carrying small items, but I'm selling it because it's a bit small for souvenirs. I've only used it once, but please refrain from purchasing if you are looking for a perfect item. If you are interested in purchasing, please feel free to negotiate.
