This is a keychain modeled after the shape of a MAG grip. I don't think anyone other than a hardcore enthusiast would be interested, but I think it's the kind of item that lets enthusiasts show off to each other. (I don't think it has any other meaning...) The approximate dimensions are 5.5 cm wide and 2.8 cm long. I've placed it in my palm to give you an idea of the size. This is a niche item, so please refrain from purchasing if you are looking for perfection or are overly concerned about details. *Shipping will be done via Yamato Nekopos, wrapped in bubble wrap and placed in an envelope.
