BE@RBRICKs are collectible figures comprised of nine parts — a head, torso, hips, arms, hands, and legs with joints that can move, which come in a range of materials, although most frequently plastic. The normal one is 70mm tall, which is also known as 100% on the size scale. Bearbricks of 35mm, or 50%, are usually sold as keychains. Larger sizes include 280 mm, or 400%, and 700 mm, or 1000%, the latter of which is the largest Bearbrick size available. Most collectors prefer the 400% and 1000% sizes.
