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 made of 100% recycled PP plastic and the lid is made of food grade PP plastic. The shades of black or white may vary, and the white option has a texture colour effect and may include tints of colour, due to the nature of the recycled material. Volume capacity is 350 ml. Supplied in a home compostable bag. Made in the UK. BPA-free.
