Frontier cutlery features handles with a unique profile for strength and to permit individual utensils to stack together. Food contact surfaces have a semi-polished finish for more enjoyable dining. Made of hard-anodized aircraft-grade aluminum, these utensils are built to go the distance - and an included carabiner makes sure they won't wander off on your journey. Durable and easy-to-clean (anodized items should not be washed in a dishwasher). Sea to Summit Guarantee is offered for the lifetime of this product.
