The concave neck and grip pinch improve comfort during sessions, while the wide round base keeps it firmly planted between hits. Available in Small (7\"), Medium (9.5\"), and Large (12\"), each with matched joint sizes and included downstems.\u003c\/p\u003e\n\n\u003cp\u003eEach size ships with a removable downstem and matching bowl — sized correctly for that version's joint. The ice pinch lets you drop in cubes for noticeably smoother pulls, and the removable downstem makes cleaning straightforward.

Medium and Large: 14mm female. The included bowl and downstem match the joint of each bong.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWhat's the difference between sizes?\u003c\/strong\u003e Small (7\", 10mm) is a compact daily driver. Medium (9.5\", 14mm) offers bigger pulls and more filtration. Large (12\", 14mm) is built for full sessions — maximum chamber volume and the smoothest filtration of the three.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDoes it come with a downstem?\u003c\/strong\u003e Yes — a matching removable downstem is included with each size.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHow do I use the ice pinch?\u003c\/strong\u003e Drop standard ice cubes through the mouthpiece. The pinch holds them above the waterline so vapor passes over the ice and cools before you inhale.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIs the glass thick?\u003c\/strong\u003e GRAV uses consistent-wall borosilicate glass throughout the line. It's well-made for regular use — not ultra-thick armored glass, but solid and reliable.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHow do I clean it?\u003c\/strong\u003e Fill with isopropyl alcohol (91%+) and coarse salt, cover openings, shake, flush with warm water. Remove and clean the downstem separately. Rinse thoroughly before use.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eTotal beginner? Read this\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWhat is a bong?\u003c\/strong\u003e A bong (water pipe) passes smoke through water before you inhale. The water cools and filters the smoke, producing smoother hits than a pipe or joint.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWhat does \"female joint\" mean?\u003c\/strong\u003e The joint is the connection point between the bong body, downstem, and bowl. A female joint is a hole the male bowl stem inserts into. Most standard bongs use female joints with male-stemmed bowls.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWhat's a downstem?\u003c\/strong\u003e A tube connecting the bowl to the water chamber. Smoke travels down through it and bubbles through the water — the bubbling cools and filters the smoke.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWhy does size matter?\u003c\/strong\u003e Larger chambers produce bigger, more filtered hits. Smaller bongs are easier to clean and more portable. Medium size strikes the best daily balance for most users.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWhat grind should I use?\u003c\/strong\u003e Medium to medium-coarse. Too fine and herb falls through; too coarse and it doesn't burn evenly. A standard 4-piece grinder produces the right texture.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSpecs\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e GRAV\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Borosilicate glass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSmall:\u003c\/strong\u003e 7\" height, 10mm female joint, 10mm \/ 2.75\" downstem, 10mm Cup Bowl\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMedium:\u003c\/strong\u003e 9.5\" height, 14mm female joint, 14mm \/ 3.75\" downstem, 14mm Cup Bowl\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLarge:\u003c\/strong\u003e 12\" height, 14mm female joint, 14mm \/ 4.75\" downstem, 14mm Funnel Bowl\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFeatures:\u003c\/strong\u003e Ice pinch, concave neck, grip pinch, removable downstem, round base\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUse:\u003c\/strong\u003e Dry herb \/ flower\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDesign series:\u003c\/strong\u003e Deco Beaker-inspired\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Clear\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GRAV","offers":[{"title":"Small - Clear","offer_id":49783697211629,"sku":"GRAV-WP-RNDBSE-SM-CLR","price":49.0,"currency_code":"USD","in_stock":false},{"title":"Medium - Clear","offer_id":49783697375469,"sku":"GRAV-WP-RNDBSE-MD-CLR","price":99.0,"currency_code":"USD","in_stock":false},{"title":"Large - Clear","offer_id":49783697408237,"sku":"GRAV-WP-RNDBSE-LRG-CLR","price":119.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0731\/6144\/1517\/files\/grav-round-base-bong.jpg?v=1776200020","url":"https:\/\/vgear.com\/products\/grav-round-base-bong","provider":"VGEAR","version":"1.0","type":"link"}
