Jacooxi Silicone Under-Sink Mat, 28 x 19 Inch Black Waterproof Cabinet Liner

A plain silicone sheet cut for the floor of a sink cupboard, laid in to keep drips, detergent runs and condensation off bare chipboard. It rolls up for cleaning and takes scissors readily where a waste pipe comes through.

• Size: 28 by 19 inches. Weight is 1.46 lb.
• Draining: ease the sheet forward, press one corner down, and collected water runs off without lifting everything clear of the cupboard.
• Resistance: silicone shrugs off water and oil alike, so soap residue wipes away instead of staining.
• Other uses: beneath a pet bowl, under wet boots by a door, as a craft sheet or a drip tray for potted plants.

The only thickness quoted is 0.1 inches, which describes flat sheet rather than a raised lip. No wall height appears anywhere in the manufacturer data, so how much liquid this holds before it overflows is unknown. Assume it slows a leak rather than containing one.

The food-grade description comes from the seller alone, with no standard or test reference alongside it.
