These Manzanita Burls work well in many different setups ranging from arid to aquatic.  The unique, gnarled shapes make them ideal for hardscape building as well as providing enrichment for arboreal and terrestrial reptiles and amphibians.  These are natural products and will vary from piece to piece, some being more bulky and round, while some are thinner and have offshoots.  The Small size range can be from 3x5" to 2x10" and anywhere in between.  The Large size range can be from 3x7" to 5x11" and anywhere in between.  Please specify for us if you want something particular and we will try to provide you with the best piece based on availability.
