This innovative chopping board set makes great use of wasted space beneath the shelf, thereby maximizing every inch of the cupboard area. The set includes three color-coded cutting boards with knife-friendly, textured cutting surfaces on both sides, stainless-steel selecting bars, and non-slip feet. These are held inside a slimline storage case that hooks onto your existing shelf and is secured at the back with two small screws (included). The case can be mounted either inside the cupboard or beneath and has a tiered design making the boards easy to select.
