The ring in this photo is also found in a tutorial on Instructables.com, where we sometimes post projects. If you're unable to make one for yourself and would like to purchase a custom made glowing ring, we're happy to help you out.
A ring like this, with batteries and an LED, is an art piece, and will not hold up to round-the-clock, everyday wear. Batteries must be removed before you wash your hands. A glowing mushroom ring would look elegant perched on your finger at a party, though.
If you order a custom light-up ring from us, the batteries will be covered in a flap of soft silicone, rather than left exposed like they were in the instructable.
