Product Details

Size

Capacity:8oz/230ml

Height:3.9" with lid, 3.2" without lid
Diameter: 2.2" at base, 3.5" at widest point

Industry standard volumes. Fits most car cup holders.

Care

Dishwasher and microwave safe to 212°F – though handwashing extends the life of the cork band.

The cork band is natural and fits snug by design – for everyday use, do not remove it. It will age, and expand and contract with washing. Don't force the band off. Handwash it and dry it upside down in a warm spot to keep it in top shape. Removing it? Watch our care video first.

Materials

Tempered glass cup, 100% recovered cork band, PP alloy lid and LDPE plug. The soda lime glass is heat toughened, contains 25% recovered glass material, and is lead and cadmium free.

Great glass cup to replace my dropped broken Keepcup from many years ago. So happy to have replaced it with the same glass cup. Arrived promptly and well packaged!

I love these cups but as expected, they can break at any moment. Two weeks in and I poured hot water to make my tea and the cup shattered.

Worked really well so far. Keeps my coffee nice and hot!

The lid doesn't **** down exactly evenly but it still doesn't spill if I turn it upside down so it's doing its job well enough.

Love my glass keepcup as much as the plastic one.

I think this is the perfect cup for almost all cold drinks, but not optimal for boba tea customers. There are no measurements that assist boba baristas when making drinks and the mid point diameter is a bit wide for smaller hands to easily handle. (I admit to having small hands.) Also, many boba lovers like an even larger volume cup size (e.g. 700ml) than the Cold Cup Longplay L size. Just saying....
