The 4.5″ Fume Square Bowl Sherlock is a compact glass hand pipe built for flower smokers who want something that stands up on its own and fits easily in a pocket or bag. The fumed glass changes color over time as resin builds up, giving you a pipe that evolves with every session. At 4.5 inches, it's small enough to stash but big enough to handle like a real pipe, not a chillum.
Key Benefits
- Stands upright between hits — the square bowl base keeps it stable on tables, avoiding the roll-off-and-break situation
- Color-changing fumed glass — the pipe shifts in color as you use it, giving you a unique look that darkens and swirls over time
- Sherlock bend keeps smoke cooler — the curved neck gives smoke a bit more travel time than a straight chillum, so hits are smoother on the throat
- Fits in a pocket without bulk — 4.5 inches means it's portable enough for on-the-go sessions without feeling like a tiny one-hitter
- Square bowl holds more than round bowls — the geometry gives you a bit more capacity without making the pipe awkward to hold
Best For
This pipe works for flower smokers who want something portable but not flimsy. If you're tired of round-bowl pipes rolling off surfaces or you just want a hand pipe that stands up between hits, this one's worth grabbing. The fumed glass makes it a solid choice for people who like their gear to develop character over time.
How to Use It
Pack the square bowl with ground flower — the flat base means you can set it down mid-pack without spilling. Cover the carb hole on the side with your thumb, light the bowl, and inhale through the mouthpiece. Release the carb to clear the chamber. The Sherlock bend gives smoke a bit more distance to cool before it hits your lungs, so you're not getting blasted with hot vapor on every pull.
After a few sessions, you'll notice the fumed glass starting to shift color. That's resin interacting with the silver or gold fuming inside the glass — it's not dirt, it's the pipe developing its own look. When the airflow starts to feel restricted, clean it with isopropyl alcohol and coarse salt, shake it out, rinse, and let it dry.

FAQ
Will this actually stand up on its own?
Yes. The square bowl base is flat enough to sit upright on a table or rolling tray without tipping over. It's not perfectly stable on uneven surfaces, but on anything flat, it stays put.
What does "fumed" mean?
Fumed glass is made by vaporizing precious metals (usually silver or gold) onto the glass during production. As you smoke and resin builds up, the fuming reacts and changes color — usually going from clear or light tones to yellows, purples, blues, or greens. Every pipe develops its own pattern.
Is 4.5 inches too small for daily use?
Depends on what you're used to. It's not a huge piece, but it's not a one-hitter either. The Sherlock bend gives you more cooling than a straight chillum, so hits are smoother than you'd expect from a pipe this size. If you want something portable that still functions like a real pipe, it works fine.
How do I clean a fumed glass pipe?
Let it cool completely, then fill a plastic bag with isopropyl alcohol (90% or higher works best) and a tablespoon of coarse salt. Drop the pipe in, seal the bag, and shake for a few minutes. The alcohol dissolves resin, and the salt scrubs the inside. Rinse thoroughly with warm water and let it air dry before using again.
Will the color-changing glass fade back to clear if I clean it?
Some of the color will lighten when you clean off the resin, but the fuming itself is permanent. The pipe won't go completely back to its original look — it'll retain some of the color shift. The more you use it, the more pronounced the colors get over time.
Does the square bowl make it harder to pack?
Not really. The flat base actually makes it easier to set down while you're packing, so you're not chasing a rolling pipe around the table. The bowl opening is still round where you pack, so it doesn't change the packing process.
Is this good for a beginner?
Yeah. It's simple to use, easy to clean, and stable enough that you're not going to knock it over between hits. The Sherlock bend makes hits a bit smoother than a straight pipe, so it's not as harsh if you're still getting used to flower. For the price, it's a solid starter piece that won't break your budget if you accidentally drop it.
