Good Cuppa Glass Cup

While the borosilicate glass is durable and thermal-shock resistant, it is still glass. We recommend carrying it upright in a cup holder or side pocket rather than tossing it loose in a bag to avoid impact damage.

The silicone lid is splash-resistant, designed to prevent spills while you are walking or driving. It is not designed to be 100% leak-proof, so it should not be submerged or stored horizontally in a bag.

Yes, the borosilicate glass construction is microwave safe. Just be sure to remove the silicone lid before heating to prevent any pressure buildup.

The double-wall design creates an air pocket that insulates your beverage, keeping hot drinks hot and cold drinks cold for longer than a standard single-wall cup. It also ensures the exterior remains cool to the touch, so you won't need a separate sleeve.

Silicone can occasionally absorb strong odors over time. To keep the lid fresh, we recommend washing it thoroughly with warm, soapy water after each use or soaking it in a mixture of baking soda and water if you notice lingering scents.

With a base diameter of 3.4 inches, the Good Cuppa fits comfortably in most standard vehicle cup holders. It is a good idea to measure your specific cup holder if you have a particularly compact or non-standard console.
