Each is approximately 3" x 2 1/8", not including the keyring,
Condition of them is good but I have tried to document 2 possible flaws, one on the McCoy keychain and one of the Sulu & Chekhov keychain. I am unable to determine if it's a flaw/scratch in the resin, or if it's simply residue from an adhesive that may have been placed there in the past. Please look at pictures and let me know if you have questions.
