Mini Cork Tunnels / Mini Cork Rounds Give your tiny terrarium inhabitants the perfect place to hide, explore, and climb with our Cork Tunnel Minis. Made from 100% virgin natural cork, these miniature cork tunnels are perfectly sized for mourning geckos, hatchling geckos, dart frogs, tree frogs, spiderlings, jumping spiders, tarantula slings, mantises, isopods, and other small invertebrates. Their naturally hollow interior provides a secure retreat while the textured outer bark encourages climbing and natural exploration. Every Cork Tunnel Mini is completely unique, with natural variations in shape, texture, and color that make each piece one of a kind. Measuring approximately 3–4 inches long with a 1.5–3 inch diameter, they're the ideal size for nano terrariums, micro bioactive setups, arboreal spider enclosures, and compact vivariums. Whether positioned upright, laid horizontally, partially buried, or incorporated into a natural hardscape, these tunnels instantly create a realistic forest environment. Unlike artificial hides, virgin cork bark is lightweight, rot-resistant, mold-resistant, and naturally durable in humid environments. It blends beautifully with mosses, leaf litter, botanicals, vines, and live plants while supporting the natural behaviors of small reptiles, amphibians, and invertebrates. Jumping spiders and spiderlings use the textured bark as an excellent climbing surface, while frogs and tiny geckos appreciate the secure shelter and elevated perching opportunities.
