All our isopods are available in quantities of 5, 10, 15, or 20 (stock permitting). Our isopods ship with sphagnum moss and cold/heat packs as appropriate. We are fully licensed to sell and ship our isopods across the United States, but some states may have restrictions in place that may prevent you from ordering. Some isopods can be chosen for your Isopod Lodge habitat kit, which makes them an incredible bargain.
