This is the most favored reasonable object used for opening bottle caps. The body is anodized in the shape of a fish bone with an aluminum alloy which keeps the product corrosion free. The fish bone is fitted with a circular metal ring. This product is used as a keychain and a decorative object to hang along with your bags' zips. They are small and can be carried anywhere in bags or pockets. These kinds of products are primarily used at home or by the skilled bartender to take caps off the bottles. Not only does this keyring look good, but it is also very helpful to securely hold small objects.
