All our isopods are available in quantities of 10, 15, or 20 (stock permitting). The most expensive species are sometimes also available in 5 counts. Check the product page to learn more. 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.
