This is our in house made Urchin. Made with a super hard form of plastisol to keep that bounce in the tentacles that they need to generate bites and also have superb durability. Other advantages of non TPE are you are able to use lire dyes and scents and also they sink a little quicker than TPE. An awesome “full cast” profile pf 25mm ball and 4.5” of total width.
