Excellent reptile substrate made from natural materials. I used this for my bearded dragon, but it didn't suit my household, so I'm selling it. It has been opened, and I have stored it in a zip-lock bag (purchased 3 months ago). I have photographed the outer bag so you can see the original material. - Type: Substrate - Weight: 1.0kg - Material: Walnut shell - Application: For reptiles and amphibians - Features: Clean and safe, easy to maintain, easy to dispose of ■ Leopard gecko ■ Russian tortoise ■ African spurred tortoise ■ Blue-tongued skink ■ Bearded dragon Thank you for looking.
