The Vesper is the precision-engineered take on a gravity bong. Where most gravity systems rely on a friction seal, the Vesper uses a threaded cap with a medical-grade silicone gasket. The result is zero air loss during the vacuum phase and a slower, more controlled draw — ideal if you'd rather meter your pull than chase a fast clear.
Hydraulic displacement does the work of pulling air for you, so you get a cooler, denser hit without the lung strain of a traditional water pipe. The standard 14mm female joint is universally compatible with the quartz bangers and bowls you probably already own.
Care: Disassemble the cap and remove the gasket before cleaning. Soak the glass in warm water + isopropyl. Don't soak the silicone gasket in alcohol long-term — it shortens its life.
Vesper vs Deco: Vesper for controlled draws and an airtight mechanical seal. Deco for fast clears and a heavier, more decorative ribbed-glass piece.
