Any recommendations? It's for DH, he's a builder and keeps a mug in his work van, but ordinary mugs keep getting broken and I've hardly any old mugs left in the cupboard, so I thought for Father's Day, the kids could get him a good quality indestructible mug for work, but it MUST be 100% dishwasher safe as he only brings the mug in on a Friday to be washed and no amount of handwashing gets a weeks worth of tea dregs out (yes it's gross, but he doesn't care -says it adds more flavour 🤢, not my mug, not my business...)
