GRAV Upline Taster – 3.5″ Borosilicate Glass One-Hitter with Ash Trap

Savor every puff with the GRAV Upline Taster – a compact 3.5″ borosilicate glass one-hitter from the Upline series, engineered for pure flavor and clean burns. Extra-thick restrictions trap ash while rippling light for a colorful, depth-filled look, with constricted airflow for smooth, drag-enhanced hits. High-quality 16mm tubing resists thermal shock – perfect for micro-dosing herb or dabs on the go, praised in reviews for “insane flavor without harshness.”

• Ash-Trapping Design – Thick restrictions catch residue for mess-free use
• Flavor-Focused Airflow – Constricted path enhances taste, cools vapor
• Durable Glass Build – 3.5″ borosilicate, 16mm tubing for shatter resistance
