Practical and well made!

I love the security of the locking carabineer. This is easy to attach to a backpack or fanny pack, and strong enough to use for any accessory.

Thank you Rachel!

Sports carabiner

This is a really good quality carabiner. I have bought others and this one has been the best keychain one I have found and well worth it.

Thank you Heidi! So glad you are loving your new keychain!

Durable and easy to see!

I grabbed a bright color so the keychain is easy to see if I dropped it, but honestly, I probably won't need it, the carabiner is very secure. It's a good length and a really lovely way to carry around important keys with an option to add more client keys as needed.
