Duralex Prisme Tumbler

Yes, they are made from tempered glass, which is specifically engineered to withstand repeated dishwasher cycles without clouding or losing its clarity.

Duralex tempered glass is highly resistant to thermal shock, meaning these tumblers can handle hot liquids safely. However, they are primarily designed as drinking glasses, so handle with care when filled with boiling water.

The geometric facets are more than aesthetic; they provide a natural, secure grip that makes the glass feel sturdy and less likely to slip, even when condensation forms on the outside.

This size is considered a 'juice' or 'small tumbler' size. It is perfect for juice, water, or a short cocktail, but it will be too small if you are looking for a large, highball-style glass for iced tea or soda.

While no glass is unbreakable, Duralex tempered glass is significantly more resistant to impact and breakage than standard soda-lime glass. If they do break, they are designed to shatter into small, blunt chunks rather than dangerous, jagged shards.
