Meant for the archery savvy, the VERMIL thumb ring is designed in versatile sizes to protect the archer's thumb and it fits over the end of the thumb. This modern classic ring can be used either RH or LH. Vermil Classic Vermil's original design features a solid string guard for comfort and protection. Great for learning. Rest the string between the lip and guard, and make sure you don't hook your thumb too far around the string. Thanks The Cinnabar Bow for this good description. Measurement For choosing the size, you can measure in two dimensions like the photos we provide on listing.
