2″ 18MM FEMALE BLACK & SLYME TRIANGLE BOWL

The 2" 18MM Female Black & Slyme Triangle Bowl is a glass flower bowl built for people who want their daily driver to hit hard and look mean. Made for 18mm male joints, it’s a go-to upgrade when you want bigger packs, better grip, and a bowl that doesn’t disappear into the rest of your setup. At about 2 inches (51mm) tall with bold black and slyme glass, it’s compact, sturdy, and loud in all the right ways.

Why You’ll Actually Use This Every Day

• Bigger, heavier snaps — 18mm female joint gives you a wider airway, so your hits feel fuller and more satisfying.
• Easy to handle when you’re baked — The triangle body and slyme glass accents give your fingers natural grip points, so you’re not fumbling a hot bowl.
• Stands out on the table — Black base with slyme glass details looks sharp next to clear glass, silicone, or color rigs.
• Comfortable pull — The bowl geometry keeps airflow open, so you don’t feel like you’re sucking a milkshake through a straw.
• Swaps in fast — Standard 18mm female joint size slips straight onto most big-tube bongs with 18mm male joints.
• No metal taste — All-glass path means your flower flavor stays true to the strain.

Best For

This bowl is ideal for people running bigger water pipes who actually clear full bowls and don’t just “taste test.” If you’ve got a thick glass base piece or a sturdy silicone bong or rig and want a bowl that matches the vibe, this one fits right in. It’s also a solid pick if your hands run a little clumsy mid-sesh and you want something with real grip instead of a tiny smooth nub.

How to Use It

Drop the 18mm female bowl onto any 18mm male joint on your bong or water pipe. Make sure the joint seats fully and sits snug and straight — you want glass-on-glass contact all the way around so it doesn’t wobble. Once it’s locked in, pack your flower in the bowl, use your regular pull technique, and let the wider joint size do the rest.

The triangle profile isn’t just for looks: it gives you three solid gripping faces, so when you’re lifting the bowl out for a clear, you’ve always got an edge or corner to grab. If you’re the type to keep a full setup laid out on a dab mat, this shape also doesn’t roll around as easily as round bowls, which keeps accidents to a minimum.

When you’re done, let the glass cool before you touch or clean it. Ash it out, tap gently if needed, and avoid banging it against hard surfaces so you don’t stress the glass or the joint.

Specifications

Fit & Compatibility

This bowl is made specifically for 18mm male joints. If your bong or rig has a 14mm joint, this will not fit directly — you’d need a proper adapter. It works best on medium-to-large water pipes where you actually benefit from the extra airflow of an 18mm channel. If you’re not sure what size your joint is, compare it to another known 18mm piece or check the specs on your main tube; a lot of larger tubes and many higher-airflow smoke shop style bongs are 18mm at the bowl.

Cleaning Advice

Let the bowl cool all the way down, dump the ash, and wipe or swab away loose residue. For deeper cleans, soak in isopropyl alcohol, rinse thoroughly with warm water, and let it dry completely before your next sesh. Keeping it clean not only makes it look better, it keeps airflow from getting clogged and preserves your flower flavor.

FAQ

• Will this bowl fit my piece?
  If your bong or water pipe has an 18mm male joint, yes — this 18mm female bowl will drop right on. If your joint is 14mm or you’re using a different style of connection, you’ll need an adapter or a different bowl size.
• How big are the hits compared to a 14mm bowl?
  An 18mm joint has a wider opening than a 14mm, so you get more airflow and room for a larger pack. That usually means denser, heavier hits, especially on bigger tubes. If you’re used to 14mm and want to step up your snap size, this is the natural upgrade.
• Is the glass thick enough for daily use?
  It’s built as a daily driver bowl, not a fragile art shelf piece. Treat it like any quality glass slide — avoid hard impacts, don’t thermal shock it with extreme temperature swings, and it’ll hold up fine for regular use. For people who tend to break things, pairing it with durable bases or silicone pipes and hybrids can help keep the rest of your setup safe.
• How do I keep the triangle shape and colors looking clean?
  Ash it out regularly so resin doesn’t bake on, and give it a quick soak in isopropyl alcohol whenever it starts to look hazy. Rinse and dry completely to keep the black and slyme glass looking sharp instead of cloudy.
• Does the triangle design change the way it hits?
  The triangle is more about grip and stability than changing the smoke itself. Functionally, what you’ll notice most is the 18mm airflow and the comfort of grabbing a flat face or edge instead of a tiny round nub when you clear the bowl.
• Can I use this with ash catchers or other attachments?
  As long as the connection point you’re sliding into is an 18mm male joint, you’re good. If you’re running a full setup with ash catchers, pre-coolers, or other accessories, just match everything to 18mm or use proper adapters. For keeping all those add-ons organized, a few extra storage and packaging pieces can help keep your station from turning into a random glass pile.
• How should I store it when I’m not using it?
  Let it cool, give it a quick clean, and store it somewhere padded or upright where it won’t roll or get knocked around. Some people keep spare bowls in small padded boxes or next to their glass jars and packaging to keep everything together and out of the way when not in use.
