4.5″ IRIDESCENT BUS RIG

The 4.5" Iridescent Bus Rig is a compact novelty dab rig shaped like a classic bus, designed for dabbers who want a conversation-starting piece that still delivers solid function. Standing just 4.5 inches (114mm) tall, this sculpted glass rig comes ready to use with a 14mm male 90-degree quartz banger included, making it a complete setup for concentrate sessions right out of the box.

Key benefits

• Grab-and-go portability — at 4.5 inches tall, this fits in your hand and travels without the stress of hauling a full-size rig
• Complete kit ready to roll — 14mm 90-degree banger included means no hunting for compatible accessories
• Rainbow iridescent finish catches light from every angle — looks different depending on how the sun hits it
• Sculpted bus design makes it a genuine shelf piece when you're not using it
• Multiple color options available so you can pick the vibe that fits your setup
• Standard 14mm joint plays nice with most bangers and accessories you already own

Best for

This rig fits dabbers who appreciate novelty glass but don't want to sacrifice function for aesthetics. It's sized right for apartment dwellers, dorm setups, or anyone who keeps their rig on a dab mat in a shared space where discretion matters. The bus shape makes it a solid gift for collectors who already have their daily driver and want something fun in the rotation.

If you're doing heavy back-to-back sessions all day, you might want something with more water capacity. But for casual use or as a secondary piece, the compact size actually works in your favor — less water means more concentrated flavor on each hit.

How it works

The iridescent bus rig functions like any standard dab rig, just with more personality. Fill the base with enough water to cover the downstem (you'll hear it bubbling when you draw), heat your included banger with a torch, let it cool to your preferred temperature, drop in your concentrate, cap it, and inhale through the mouthpiece.

The 90-degree banger angle on this rig means the nail sits perpendicular to the joint rather than angled. This is standard for smaller rigs and keeps everything compact. When you're loading concentrates, a dab tool helps you portion out just what you need without making a mess.

The iridescent finish is applied to the outside of the glass, giving it that rainbow oil-slick effect that shifts colors as it moves. It's purely aesthetic but makes the piece pop on a shelf or under LED lighting. The sculpted bus shape means there are some curves and details that'll need occasional attention during cleaning, but nothing a soak in isopropyl won't handle.

Specifications

What's included

• 4.5" iridescent bus glass rig
• 14mm male 90-degree quartz banger

Compatibility notes

The 14mm male joint accepts any 14mm female banger, nail, or adapter. The included banger gets you started, but you can swap it for a different quartz banger or thermal banger down the line if you want to upgrade. The 90-degree joint angle is common for compact rigs, so finding replacement parts won't be an issue.

For carb caps, standard bubble caps or directional caps sized for your banger will work fine. The rig's small footprint means you'll want to keep your accessories organized — a silicone dab mat helps corral everything in one spot.

Care and cleaning

Let the rig cool completely after use. Pour out the water, rinse with warm water, and for deeper cleans, fill with isopropyl alcohol and coarse salt, shake gently, then rinse thoroughly and let dry. The sculpted bus details can trap residue in crevices, so occasional soaking helps keep it looking fresh. Store upright on a stable surface to protect the iridescent finish.

Frequently asked questions

Does this come with everything I need to start dabbing?

Almost — the rig and banger are included, so you just need a torch, a dab tool, and your concentrates. If you're building a setup from scratch, grab a butane torch and a concentrate jar to store your material, and you're set.

Is the iridescent finish durable?

The finish is applied to the exterior glass and holds up well under normal use. Avoid abrasive scrubbing on the outside when cleaning — stick to soft cloths or gentle rinsing to preserve the rainbow effect. The inside cleans normally with alcohol and salt.

Can I use a different banger with this rig?

Absolutely. Any 14mm female banger with a 90-degree angle will fit. The included banger works fine for getting started, but many dabbers eventually upgrade to a thicker quartz option for better heat retention.

How much water should I put in it?

Just enough to cover the bottom of the downstem — usually about half an inch to an inch of water. You want to hear bubbling when you draw but not have water splashing up toward the mouthpiece. With compact rigs like this, less is usually more.

Is this rig fragile because of its shape?

It's glass, so treat it accordingly. The sculpted bus shape has some protruding details that could be vulnerable to impacts, but it's no more fragile than any other small glass rig. Keep it on a padded surface when not in use, and don't leave it on the edge of tables.

What colors are available?

Multiple iridescent color variations are available. The rainbow finish means each piece catches light differently — contact for current stock if you're looking for a specific colorway.

Is this good for a beginner dabber?

It's a solid starter piece. The included banger means you don't have to figure out joint sizes and compatibility right away. The small size makes it easy to handle, and if you're still dialing in your technique, you're not risking an expensive piece while you learn.
