These 100 percent renewable knives are part of the Cutlerease Dispensing System that provides clean, hygienic cutlery ready to use for guests, visitors and customers. Cutlerease's innovative design dispenses clean cutlery one piece at a time. Tape tabs offer easy pickup and loading of bound knives into a dispenser cartridge (sold separately) without having to touch any part of the cutlery. Handle-first delivery ensures guests touch only the handle of the knife they are taking. Knives are made of PLA (Polylactic Acid), a plant-based plastic, and designed for use with foods up to 120 degrees Fahrenheit.
