750ml Square Extra Flint Spirit Bottle with Heavy Base

Engineered by Yuzhou Glass, this tapered square bottle features crystal clear clarity in premium Extra Flint Glass with an authoritative heavy base and distinct architectural profile. The vessel provides complete production agility with full support for custom neck finishes—ranging from bar top stoppers to GPI threads—as well as private custom mold development spanning from Demi Bottle (375ml) line extensions to standard Fifth Bottle (750ml) and large Magnum Bottle (1.5L) formats. Formulated for premier shelf presence across high-proof whiskey, vodka, gin, and artisan rum, it delivers a high-end tactile experience while remaining 100% recyclable, endlessly reusable, and an eco-friendly glass packaging alternative to commercial plastic.
