Only fits on round standard sized house keys. Very cheaply made.
These only fit on a standard sized house key with a round top. I bought it to go on a car key with a small black plastic top and it would not close over it. It broke at the top seam easily WITHOUT forcing it to close. Also, this might be difficult for someone with arthritis to install on their key themselves or get it back off again. It would definitely be difficult for anyone to get it on a key ring. It did seem like it would function on a regular sized key but I did not try it. It is very cheaply made of hard molded plastic and the one I tried broke in half easily at the hinge. Absolutely not worth 4.95 for 2 due to the low quality. These would be appropriately priced at 2 for 0.99. Returned through Amazon.
