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. Made from 100% pre-consumer recycled material. The shades of black or white may vary, and the white option has a texture colour effect, due to the nature of the recycled material. Volume capacity is 350 ml. Made in the UK. Packed in a home compostable bag.
