Please Read :) Felt Ball Key Chains are a great way to add a little color to help you find those incessantly lost keys! ;) Choose from 60 colors, see the color chart photo & name your color choice(s) in the “Personalization” section of this listing. All keychains are made with 2.5 cm wool felt balls, that measures roughly under an inch so the sizes are as follows: 3 felt balls = roughly 3 inches 4 felt balls = roughly 4 inches 5 felt balls = roughly 5 inches 6 felt balls = roughly 6 inches Have another length in mind? Message me! I am happy to do any size you’d like :) Length does not include the silver ring/clasp. There is a photo showing your two options. The suggested us of the a metal D-Ring on a Key Ring is for your keys. The suggested use of the metal Swivel Lobster Clasp is to hang from your car mirror or purse, or anywhere else you’d like a pretty charm. Can be scented with essential oils for free! Choices are in the drop down menu. The drop of oil will leave a mark, so I will apply it as inconspicuously as possible between two felt balls. Just simply re-scent in that same spot & only one dot of oil will ever be seen on your beautiful keychain! I use top quality pure essential oils with no filler oils. (Sweet Citrus is a 50/50 blend of orange & pink grapefruit). Want 10% off every single order from me?!?!?
