GL BirdCage
GL Birdcage
The GL Birdcage stands out for its distinctive dual-form construction, combining two stacked cylindrical sections—one 60 mm and one 51 mm—to create an architectural presence with layered depth. At 11.5 inches tall, the silhouette narrows as it rises, giving the design an elegant, vertical rhythm.
Inside the upper section, sculpted internal detailing resembles a delicate cage-like formation, contrasted by a compact multi-arm structure in the lower section. Together, these elements create a complex visual pattern that moves beautifully as light passes through the form.
A reinforced stemless body keeps the lines clean and uninterrupted, while the bent-neck mouth end with a subtle constriction adds an intentional sculptural curve to the profile. Two color lip wraps—one at the mouth end and one at the base—frame the design and anchor the clear vertical body.
Originally released in 2018 as Version 2.0, the GL Birdcage carries the GL303 Colorado Certified Gold Label, marking its build quality and signature GL303 shaping.

Why It Stands Out
The GL Birdcage is known for its layered vertical architecture and its combination of two distinct internal formations. The contrast between the cage-like patterning and the compact multi-arm detailing gives the form a dynamic, sculptural identity. Paired with color-wrapped accents and a bent-neck silhouette, it feels both intricate and clean—a standout in the GL303 collection.
Care & Cleaning
Rinse or soak with warm water and a gentle glass-safe cleaner. Avoid abrasive tools to preserve the internal detailing, color wraps, and clarity. Allow the form to dry completely before storing. Avoid sudden temperature changes.
