Ichendorf Milano Venezia Ottico Water Tumbler

Not at all. The texture is subtle enough that it doesn't trap residue, making it easy to wipe clean with a standard sponge or bottle brush.

While the borosilicate glass is durable and heat-resistant, these tumblers are primarily designed for cold water and beverages. We recommend sticking to room temperature or chilled drinks to ensure the most comfortable handling.

This is a slightly smaller, more refined size than a typical 12-16 oz kitchen glass. It is perfectly proportioned for a standard serving of water, juice, or a casual cocktail.

To keep the glass clear and prevent potential stress fractures, use the 'delicate' or 'glassware' cycle on your dishwasher. Avoid high-heat sanitizing settings to ensure the longevity of the material.

Actually, the opposite is true. The textured design provides a tactile grip that makes the glass feel secure and balanced in your hand, even when condensation forms on the exterior.
