Stack Up Cross New The Stack’up Cross collection is an extension of the Stack’up collection. It retains all the benefits of the tempered tumbler, but with an extra touch of style. Stackable, resistant to mechanical and thermal shock – the new-look Stack’up Cross is a great option for renewing just part of the basic glassware in bars and restaurants. This cut crystal style is still very popular with bars. The vintage aesthetic adds a much-appreciated retro touch to any cocktail. Mixologists will love this combination of functionality, price and style.
