Cast iron products get very hot. Use the heat-resistant glove with anti-slip coating to avoid burning yourself. The glove can be worn both left and right and is one-size fits all. You are buying one glove (it is all you need usually) and please note that it is a snug fit so may not suite very large hands. This glove allows you to hold hot BBQ parts and cast iron cookware. It is not suitable for handling food or hot fuel.
