DMUK Stainless Steel Travel Mug
The mug is 16cm tall (that's 6 inches in old money), and comfortably holds a large cup of tea. It is made of stainless steel, lined with polypropylene and fully foam insulated to keep your brew warmer for longer.
It has a drink-thru lid, or you can take the lid off and drink as if it's a normal mug!
