5. What kind of packing materials does Artisan Cutlery use?
We are committed to using eco-friendly packing solutions whenever possible. We use air-filled pillow bags that efficiently pack into boxed shipments and reduce the amount of packing material needed for each order. We also use 100 percent biodegradable starch pellets as packing materials. These static-free pellets have the look of old-fashioned plastic packing peanuts but are made to degrade quickly in landfills and are completely petroleum, CFC, and HCFC-free.
