Vermil Classic Thumb Ring

Vermil's original design, featuring a solid resin string guard for comfort and protection, is great for learning how to shoot using a thumb ring. To use the thumb ring, rest the string between the lip and guard, making sure to not hook your thumb too far around the string. Available in black or ivory, please specify. Available in 18 mm x 21mm, 19mm x 22mm, 20mm x 23mm, 21mm x 24mm, and 22mm x 25mm, please specify. See manufacturer charts below for sizing and measurements.
