Got the ring yesterday in the mail...the product pic doesn't really show the actual ring very well. It's a "one size" ring - meaning there isn't a closed end - it has more of a feel of a toy ring. The side says #11 which could be a ring size, but this will fit on almost any finger size. I have gloves with my costume and the ring was a little large for my ring finger so it works well with the gloves. There is a tiny button on the inside that turns the ring on and off - works well and is pretty bright (in a dim club or party it will definitely have a nice green glow). The ring is plastic with some grey paint on the sides (it's not well done - may use a black marker to cover that). For a few dollars with free shipping you can't beat it.
