Initial Lock Pendant Necklace

There are some reviews saying the letter lock is small but it’s appropriate size for the delicate design of the necklace. The clamp is large so this makes it very easy to put on - especially with long nails. My only complaint is the length of the chain itself is longer than I’d like and there’s no option to adjust the length (no additional loops at the end). I am allergic to nickel and did experience some mild irritation like symptoms from it; but not enough to stop wearing it because it’s a cute everyday or casual fit necklace
