It starts black. Then your drink arrives and things get interesting.
Pour in something hot and the design reveals itself — a colour-changing mug that genuinely surprises people every single time. The kind of thing that makes someone do a double-take across the office kitchen.
330ml capacity. Ceramic. Works with tea, coffee, hot chocolate — anything warm enough to make the magic happen.
- Heat-sensitive colour-changing design
- 330ml capacity — a proper mug, not a thimble
- Ceramic construction
- Makes an excellent gift — the reaction is half the fun
Buy it for yourself. Pretend you bought it as a gift.
