Bio Vine is a completely synthetic, non-toxic vine that looks and feels like a real vine. It is perfect for arboreal reptiles and amphibians. Bio Vine is bendable and twistable and can be twisted together with different sizes of T-Rex Bio Vines to create a natural look in your terrarium. Wrap it around plants, branches or hang it in your terrarium using T-Rex Suction Cups (#81266). Bio Vine can get wet but do not submerse it in water. It is also available in a 5mm thickness (#81290). Along with the classic brown vine, Bio Vine Moss (#81252) is also available which gives the appearance of a vine covered in moss.
