This clever set from Joseph Joseph gives you a complete prep center that fits together for compact storage. Three color-coded, flexible prep mats let you work with a variety of food, keeping meat, fish, vegetables,dairy, etc. separate if you wish. They're easy on your good knives and flexible enough to let you funnel food into pans and bowls. The tempered glass mat can be used underneath the flexible mats or as a stand-along prep surface or counter protector for hot pans up to 530 degrees F. The glass mat features non-slip rubber feet that hold all four mats together for storage. Glass mat is dishwasher safe, hand-washing recommended for the flexible mats. Each mat measures 16" x 12".
