"Ready to ship! I ended up having to airbrush the fabric because I wasn't able to find anywhere that prints on glow-in-the-dark fabric. This was made with a pattern by Beep's Creatures https://www.etsy.com/listing/1395595361/ This tail measures 22.5 inches long. Currently it doesn't have any straps or attachment, it's intended for you to sew directly on your costume. I can add attachment if needed :) ** Added to clarify-- this is not actually radioactive, it's made from glow in the dark fabric."
