Bunmery Diatomite Dish Drying Mat, 23.2 x 15.4in, Dark Grey, with Sanding Tool

Diatomite pulls water straight off draining crockery and lets it evaporate from the face of the stone, so the surface under a rack stays dry rather than staying damp the way a folded tea towel does. Uptake is rated at 150% of the mat's own mass.

Two sizes appear in the source. The headline calls it 24" x 16"; the specification records 23.2" long by 15.4" wide. Plan the worktop run around the smaller pair of figures. Weight is 2.2kg.

Supplied with it are a sanding tool for refreshing the surface, an anti-slip pad plus printed instructions. Dark liquids stain the stone — coffee and red wine are named specifically, and spills of either should be kept off it. A faint scent and a dusting of powder on a new mat are described as normal; rinse and dry the surface before first use.

One claim to treat with caution: the description says the mat rolls down to 15.35" by 4.25" for storage, which is difficult to square with a rigid diatomaceous earth slab. The collapsible behaviour should be considered unverified.
