Equalizes moisture, gentle to fragile eggs. Maintain a tropical habitat's proper humidity with highly absorbent coconut husk, which retains moisture without significant decay. This 100% natural material is thoroughly non-toxic and non-abrasive, and is fully biodegradable. Coconut husk naturally expands to many times its packaged size, making it a safe landing cushion for reptiles that love to jump. Also an ideal medium for egg laying, thanks to its soft texture and easy burrowing. Packaged in compressed blocks to save valuable shelf space.
