• BPA-free plastic made to food-grade standards — gives you a clearly specified material for regular handling.
• Enhanced ergonomic grip — shaped for handling and comfort in the mouth.
• Made and rigorously tested in the UK by specialists with over 150 years of experience — brings UK manufacture and specialist testing together.
