This is a massive, transparent, red lucite spiral bangle bracelet. This hard-to-find bangle is featured on page 121 of Plastic Bangles by Lyn Tortoriello and Deborah Lyons. It measures a whopping 1 5/8" wide with 3/4" thick walls. It measures approximately 2 5/8" across the opening and 8" around the inside.
The bracelet is in excellent condition with none of the rough edges commonly found on these bangles. The mark on the inside of the bangle is not a flaw. It is a "sprue" or mold mark made during manufacturing.
The color of this bangle is truly spectacular. This bracelet would best fit a medium to large sized wrist. I have a small wrist and you can see how it fits me in the last two pictures. I currently have two of these available.
