Ohhh yes, our weather proof stickers make the perfect "mailed out" gift. Light enough to send in a "regular" Forever stamp envelope, these are our go to gifts to just send some ALOHA to our pals on the mainland. And yup! They're weather proof and waterproof. Meaning they can be stuck on to any surface and stay there safely! An Eden exclusive. Dimensions: 2.87" x 2"
