Unbreakable? For sure! This shiny stainless steel mug with 270ml filling volume is perfect for all life situations in which ceramic mugs can break quickly. Whether for camping or in the workshop, the mug remains intact if dropped or tipped over. Due to the double-walled construction of the mug, the outside of the mug does not heat up and drinks stay hot or cold for a longer time. Laser engraving as customisation makes it an elegant advertising and brand ambassador.
