Delta 隔熱杯套

I spilled coffee on my old sleeve and figured I'd try this replacement before buying a whole new mug. Fits snugly and the ThermoSkin really does its job — I can hold it comfortably even with boiling-hot tea inside.

The ThermoSkin sleeve fits snugly and makes holding the mug actually comfortable instead of burning my hand after the first sip. Wish I’d grabbed one sooner, keeps the heat where it belongs.

The mug kept sliding all over my desk because the old sleeve had stretched out — this one fits snug and actually stays put. I'm still holding my coffee comfortably ten minutes later, and the heat insulation is doing its job without burning my palm.
