Brittany Recreational Bristle Dartboard Features Self-Healing Sisal Fibers for Years of Use. An ideal entry-level bristle dart board, the Nodor Brittany is designed specifically for steel-tipped darts. The regulation-size board offers such features as a movable number ring that prolongs the life of the board, easy-to-read numerals on the ring, and self-healing sisal fibers that hold up to years of use and abuse. Unlike tournament boards, however, the Brittany doesn't have an angled spider nor a staple-free bulls-eye, making it more suitable for recreational play than tournament use (Nodor produces a full line of tournament boards for serious players). But for a basement rec room or garage, the Brittany is a perfect fit. The board measures 18 inches in diameter and 1.5 inches thick
