Can't find the keychain version of a cut out on my site...order the pendant and one of these as well. Some keyrings are special order and others I have not made yet. All pendants are available as keyrings although some of the more delicate designs I do not recommend.  I will e-mail you if I have any concerns with your choice.  As shown in the picture, keyrings are standard split ring style and bails are adjusted for strength.
