3 sizes for separate tasks: large 14.99 x 10 in, medium 12 x 7.8 in, small 9.5 x 6 in. Grinding area for garlic and ginger: the two larger boards include a built-in grinding area for garlic or ginger. the small board does not have this feature. Non-slip and dishwasher safe: non-slip rubber feet and integrated handles help keep the boards stable on the countertop. made from thick, heavy-duty plastic and non-porous design, they are dishwasher safe. Reversible and knife-friendly: double-sided design with a juice groove side to catch liquids and a flat side with more cutting space. both surfaces are strong and knife-friendly. use scenarios: - garlic or ginger prep: use the large or medium board with the grinding area to process aromatics while keeping other ingredients ready on a separate board. - juice management: slice or dice fruits and vegetables on the flat side, using the juice grooves to catch runoff. - organized multi-task prep: assign each board to a different task (for example produce, ready-to-eat items, and proteins) to reduce cross-contamination and improve workflow.
