These chips are approximately 1/4 inch long or smaller. Last photos show how much is in a typical ounce batch of shells. These abalone would work nicely in sea life decor or in various craft, resin, or mosaic projects. Suitable for use in salt water aquariums (NOT freshwater) and items should be THOROUGHLY rinsed in cold water (ONLY water) beforehand and consult with a salt water aquarium expert first. Out of country buyers I am sorry but sealife cannot be legally shipped outside of the United States due to extensive paperwork and fees required.
