This is a cute, large key ring featuring an Army Bomb design. Please be aware that this is a foreign product, so there may be some imperfections in the manufacturing. Please purchase with this in mind. I have never taken it outside since I bought it, but there are small stains and what appear to be ring marks on the black rubber part. Please check the images.
