Hello! Thank you so much for visiting my shop! These shaker charms are made with resin, glitter, dyes, paint, & mica powders. Since they are hand made each will be different. Expect imperfections like bubbles, dust, & drips. These shaker charms will break if you drop them. It is not recommended to put them on keys, backpacks, or purses unless you are okay with them possibly breaking. These shakers are dry so no liquid in them. I sell them cheaper till I can learn how to make them more sturdy. Disclaimer: I am not responsible for any damage in transit. No returns after orders have been placed. If you have any questions please contact me. Message me here or Instagram & Twitter @softsleepyghost Thank you! Planet Shaker Charms
