Made of real walnut, it adds a natural touch to the interior decoration of the jumping spider terrarium and can serve as a shelter for jumping spiders and other small animals. Our jumping spider cave has a strong attraction with powerful neodymium magnets to ensure that it will not fall accidentally. It is easy to install. You can use additional magnets to fix the cave on the top of the enclosure or anywhere else. Due to the characteristics of natural materials and handmade, the appearance and size may vary slightly. This uniqueness not only shows the charm of nature, but also provides a comfortable living place for your pet. Note: Made of natural materials, do not use with liquids as this will damage the product)
