These are handcrafted LED lamps and come in three models. They look pretty neat and a little scary too as though one of those things from the movie The Ring. Designers of this lamp are the Hoop Pool & Loop. Each model is available in a limited edition of 75 pieces. The materials used are polyester resin, urethane coating along with the LED.
