AFM Double Color Bubble Glass Carb Cap

The AFM Double Color Bubble Glass Carb Cap is a straightforward, reliable option for anyone running a 25mm banger. The bubble shape creates a tight seal over your nail, keeping heat and vapor locked in while you draw. Two-tone worked borosilicate glass gives each cap a clean look, and the construction is solid enough to handle regular use without worrying about it. At $10 it's a practical choice — a good carb cap makes a genuine difference in how efficiently you vaporize your concentrates, and this one delivers that without overcomplicating things.

Highlights:
• Bubble shape for a tight seal on 25mm bangers
• Double color worked borosilicate glass
• Available in Mint, Pink, Purple, Ink Blue, and Slime
• Improves concentrate vaporization efficiency
• Heat-resistant borosilicate construction
• Intended for legal use only

Bubble caps work best at slightly lower temps where the seal really traps vapor. If you're running high heat, you may want a directional cap instead for more airflow control.
