Rolling papers

We'll only email you about this product — no marketing.
The Glass Filter Extra Long is a reusable borosilicate glass tip that slots into your joint for cooler, cleaner draws every time. Made by Eko Puffs, these 65mm filters use a twisted internal smoke path — either balls or a pyramid design — to break up and cool smoke before it hits your lips. At 8mm diameter, they fit standard rolling papers and pre-rolled cones without fuss. One filter replaces hundreds of cardboard roaches, and unlike paper tips, borosilicate glass doesn't absorb saliva, so your joint stays dry from the first puff to the last.
Both variants are the same length (65mm) and diameter (8mm). The difference is the internal structure that breaks up the smoke path:
| Variant | Internal Design | Draw Feel |
|---|---|---|
| Balls | Small glass spheres inside the tube | Slightly more resistance — smoke swirls around each ball, giving it more time to cool. Best if you prefer a slower, more deliberate draw. |
| Pyramid | Angular glass formations inside the tube | Marginally more open airflow with sharp directional changes. Good if you like a bit less restriction but still want the cooling effect. |
Honestly? Both do the job well. The Balls variant gives you a touch more filtration resistance, which some people prefer because it slows you down slightly. The Pyramid feels a fraction more open. If you're buying your first glass filter, the Balls is the one we'd nudge you towards — the extra turbulence makes the cooling effect more noticeable.

Complete your rolling setup with slim rolling papers and a decent grinder. A fine, even grind makes a real difference to airflow through the glass filter — chunky bits can block the twisted path and make the draw feel tight. The RAW Classic King Size Slim papers and the SLX Grinder are popular pairings at our counter.
A glass filter cools smoke by forcing it through a twisted internal path that increases contact time with the cool glass surface, delivering noticeably smoother draws compared to cardboard roaches. Cardboard roaches do one thing: stop plant matter from hitting your tongue. That's about it. They don't cool smoke, they get soggy within minutes, and by the end of the joint you're basically sucking on wet cardboard. We've watched people at the counter tear up business cards, train tickets, even receipts. It works in a pinch, but it's not exactly a refined experience.
The Eko Puffs Glass Filter Extra Long addresses all of those shortcomings. At 65mm, it's noticeably longer than most glass tips on the market — standard ones tend to sit around 30–40mm, making this roughly 60–115% longer than typical alternatives. That extra length means the smoke travels further through the twisted internal path before reaching your mouth. More distance equals more cooling. You can actually feel the temperature difference on your lips compared to a short tip or a paper roach. The glass itself stays cool to the touch for most of the session, and even when it warms up, borosilicate handles heat beautifully — it's the same stuff lab beakers and good kitchen glassware are made from. According to the European Monitoring Centre for Drugs and Drug Addiction (EMCDDA), reducing combustion temperature at the point of inhalation is one practical approach to harm reduction for those who choose to smoke.
The honest limitation: glass tips add a small amount of weight to the end of your joint. With a 65mm filter, you'll notice it more than with a stubby 30mm tip. If you roll thin joints, the balance shifts a bit. It's not a dealbreaker — just something to be aware of. Roll slightly firmer near the filter end and you'll be fine. Compared to something like the MouthPeace by Moose Labs (which uses activated carbon filters), the Eko Puffs is simpler — no replacement filters to buy, nothing to slot in. Just glass, rinse, repeat.
Using the glass filter extra long takes about 30 seconds of setup — place it at the end of your rolling paper and roll as you normally would. Here's the full process step by step:
Over 80% of customers who buy a glass filter extra long come back for a second one within three months — usually as a gift. We've sold glass tips for years, and the number one thing people tell us when they return is: "I can't go back to cardboard." It's one of those small upgrades — costs almost nothing, lasts ages — that genuinely changes how your joint feels. The extra-long 65mm version from Eko Puffs is the one we keep behind the counter for ourselves. The standard-length glass tips are fine, but once you've tried 65mm, the short ones feel like they're not doing enough. If you want to order one for yourself, the Balls variant is where most first-timers start.
One thing we always mention: don't put it in your pocket loose with your keys and coins. Borosilicate is tough — it handles thermal shock that would crack regular glass — but a sharp knock against metal can still chip it. A small padded pouch or even a glasses case keeps it safe. We've seen customers go through the same filter for over a year with basic care. Drop it on tiles, though, and you're sweeping up glass. Treat it like you'd treat a decent pipe — with a bit of respect — and it'll outlast dozens of packs of cardboard tips. Get yourself a small carrying case from our Accessories category and you're sorted.
Run hot water through it after each session. For resin buildup, soak in 90%+ isopropyl alcohol for 10–15 minutes, then rinse with hot water. A pipe cleaner fits inside the 8mm tube for stubborn spots. Clean it regularly and it stays clear indefinitely.
Yes. The 8mm diameter matches king-size and standard rolling papers. It also fits most pre-rolled cones designed for 8mm tips. Slim papers (5–6mm) will be a loose fit — stick with regular or king-size for the best seal.
Borosilicate glass is non-porous, chemically inert, and used in laboratory and medical equipment precisely because it doesn't leach chemicals. It handles temperatures well above anything a joint produces — rated to around 500°C for thermal shock. No coatings, no plastics, no off-gassing.
Both cool smoke through a twisted internal path. The Balls variant has small glass spheres that create more turbulence and a slightly tighter draw. The Pyramid variant uses angular glass shapes for a marginally more open airflow. Cooling performance is similar — it comes down to draw preference.
With regular cleaning and careful handling, a borosilicate glass filter lasts a year or more. The glass doesn't degrade from heat or resin. The only risk is physical impact — dropping it on a hard surface can crack or shatter it. Keep it in a padded case when not in use.
Yes, and at 65mm you notice it more than with shorter glass tips. The twisted internal path forces smoke to change direction multiple times, increasing contact with the cool glass surface. It won't make hot smoke cold, but the difference compared to a cardboard roach is obvious on the first draw.
It's designed for joints and cones. At 8mm diameter and 65mm length, it won't fit standard bong downstems or pipe bowls. Stick to rolled joints and pre-rolled cones for the intended fit and function.
