Khalil Mamoon Obsidian Mismatch 7621 – 85 cm, Engraved Column & Crest Tray

Obsidian Mismatch 7621 — 85 cm KM with deep-engraved oxide column, crest tray and a red-gold calligraphy base

What this is, why it helps, how it works, why get one

This tall Khalil Mamoon marries café-level performance with dramatic, hand-worked metal. The long tapered column is deeply engraved and finished in a warm oxide tone; inside, a straight Egyptian down-stem keeps the pull naturally open, and the classic single-ball purge clears the chamber in one breath. A heavy bell base wrapped in maroon and gold stabilises the water so smoke stays cool and consistent. If you want unmistakable KM feel with standout styling, the Obsidian Mismatch 7621 delivers.

What sets it apart

• Open Egyptian draw from a straight down-stem — quick cloud ramp and flavour-forward pulls.
• One-breath purge via the KM single-ball valve to reset the chamber instantly.
• Deep-engraved oxide column adds grip and presence; wide etched crest tray improves ash control.
• Stable bell base — weighty glass with maroon/gold calligraphy adds thermal mass for steadier temperature.
• Hose hanger loop on the stem for tidy resting between pulls.

Fit & compatibility

• Base neck: KM large ≈ 45 mm (use a large base grommet). See Khalil Mamoon Base Grommet.
• Bowls: Includes a traditional Egyptian bowl for foil. For HMDs, pair a compatible phunnel from Phunnel Bowls.
• Hose port: Standard KM male (~11 mm). Prefer washable? Browse Silicone Hoses.

How to dial it in

• Water line: 15–20 mm above the down-stem bell for an open, quiet draw.
• Foil packs: level pack to the rim, tight foil, two 26 mm cubes; add a third after 5–7 minutes if needed.
• Purge: steady exhale fully clears; half-purge to refresh flavour mid-round.

Craft & performance

Hand-built in Cairo on a stainless-steel core with oxide-tone plated exterior. The long, engraved sections are easy to hold when warm, and the heavier bell base evens the heat curve so flavour holds deeper into the session.

Care & upkeep

• Rinse stem and base warm with mild detergent; use a soft nylon brush for the down-stem.
• Avoid abrasives or strong alkalis on plated and painted areas; dry thoroughly after cleaning.

Quick fixes

• Harsh start: lift HMD lid 10–15 s or edge a coal; for foil, ease the pack.
• Thin clouds: fully light coals; add a third cube; check seals and water level.
• Air leak: refresh bowl/base grommets and re-seat the stem and hose.
