This is a traffic safety association reflector in the shape of a charm. I received it when renewing my driver's license, but I haven't used it and have stored it in a dark place. How about using it for nighttime walks or running♪ I will send it as is in a mini-letter envelope via regular mail. I will not use any cushioning material, so please consider this if you understand! Instant purchase is OK ◡̈♥︎
