Double-wall insulated tumbler with a secure twist-on spill-proof lid. The lid clips closed to better prevent spillages, and is manufactured without silicone for a fully recyclable mug. The tumbler is 70% recycled in total, with a recycled mug with black inner layer, and a standard lid. The shades of black may vary due to the nature of the recycled material. Volume capacity is 250 ml. Supplied in a home compostable bag. Made in the UK.
