Brass Tubes - Diamond Knurl RB/FTN (5 Sets)

Keep your bench stocked with replacement brass tube sets sized for the Jr Gentleman II two-tube platform. Each pack includes 5 complete tube sets — enough for five finished pens — so a mis-drilled blank or a big batch of builds never stalls a production run waiting on a reorder.

These are the correct tubes for every kit in the Masterpiece pen kit family, all built on the same Jr Gentleman II two-tube platform, for both the rollerball build and the fountain pen conversion:

• Diamond Knurl Rollerball Pen Kits

• Infinity Rollerball Pen Kits

• C Series Rollerball Pen Kits

• Band-It Rollerball Pen Kit

Why Turners Keep These On Hand

• One tube style covers the entire Masterpiece lineup — Diamond Knurl, Infinity, C Series, and Band-It — no need to stock a different tube for each kit
  

• Perfect for re-tubing a blank after a drilling mistake, or building ahead for craft show inventory

• A pack of 5 sets keeps a full production run stocked without a mid-batch reorder
