A 12″ clear beaker with a 14mm joint, bundled with a bamboo rolling tray.

This is Human Grade’s 12-inch clear beaker paired with a bamboo rolling tray, sold as one bundle. A beaker base is the forgiving shape – wide footprint, hard to knock over, easy to clean – and the 14mm joint is the most widely supported size, so replacement bowls and downstems are easy to find.

The tray is the part people underestimate. Having a defined surface means grinder, bowl, lighter and glass all live in one place instead of migrating across a coffee table, and bamboo wipes down rather than staining like untreated wood.

Specifications

What to check before you buy

• 14mm is the joint size, so any 14mm bowl or downstem fits. Confirm the joint size of accessories you already own before ordering more.
• A 12-inch beaker needs a cleaning bag that can seal around it – measure your setup if you clean with a bag system.

Care

Empty the water after each use rather than letting it sit, rinse regularly, and use cleaners intended for glass. Avoid sudden temperature swings – do not pour boiling water into cold glass. Wipe the bamboo tray with a lightly damp cloth, never soak it, and dry it promptly.
