Jurassic cork branches have an interesting look, with a coarse bark texture, are heat treated and completely natural. Smaller branches are available in a 10 x 12" polybag, with 5 or 7 smaller cork bracnhes, approx 6 to 8" L, and 1" to 2" in diameter. Specifically for for smaller terrariums with spiders, geckos, frogs and smaller snakes. Excellent for climbing, perches and basking for all reptiles and other animals. Cork branches are antimicrobial, resistant to mold, and do not decay in high humdity tanks. Also excellent for dry/desert tanks.
