us thing — it's a piece you set out, not something you hide — but the engineering matters too. At 5mm wall thickness, the glass mass holds the seal under its own weight, creating a traditional glass-on-glass friction fit that gives you immediate, high-volume air displacement. Translation: it clears fast.
If you're choosing between this and the Vesper, the difference is draw character. The Deco moves a lot of air quickly with low resistance. The Vesper meters airflow more carefully through its threaded gasket. Pick based on which feel you prefer; neither is "better."

Glass-on-glass friction seal — no rubber parts to wear out
Care: Use 99% isopropyl + coarse salt to scrub between the external flutes — the texture is part of the look but it traps residue. Rinse with warm water.
