Reviewers commonly describe Threshold glasses as solid and heavy with thick bottoms, giving them a sturdy, well-made feel.
Threshold sets commonly serve 4, 6, or 12 people. Typical offerings include 12-piece sets (often six short and six tall tumblers) and smaller 4-piece packs; single glasses are also sold separately.
Short tumblers typically hold about 12–13.3 fl oz, while tall tumblers usually range from roughly 14 to 16.75 fl oz.
The items are made of glass. Many listings highlight BPA-free and lead-free construction, and some styles are described as being made from 100% recycled glass.
