510 Large Honeycomb Wide Bore Drip Tip or Mouth Piece F5

Super slippery and soft  and comfy on the lips.

Epoxy Resin 

The Honeycomb makes it look kinda cool and shiny

FYI - Your Innokin Tanks... with the little ramp to the tip... these look dorky!  It leaves a weird space - no one will notice, but you, but it's dorky... check photo for details
