Pen Tubes (pair)
How good are these pen tubes?
I think that ALL V.2 scribers should be fitted with pen tubes-- and that's why I've priced them at barely above my cost to manufacture them.
Milled from a single piece of stainless steel on a Swiss machine. I guarantee it won't bend!
Pen Tubes save you money because from now on you will use V.2 pen refills ($6.50 each) instead of V.2 pens ($10.00 each). This saves you $3.50 every time you replace a pen. Your savings add up fast.
Pen Tubes also allow you to change a dead pen "on the fly" -- without removing the arm from the scriber, or re-setting pen length. You'll work faster and more accurately with the Pen Tubes. When a pen runs out of ink, just unscrew the cap, remove the dead pen, replace with a fresh pen refill, replace the cap, and keep scribing! Fast.
Each pen tube comes with a tube cap. The pen tube cap is a tire valve stem cap— and you can buy replacement caps from this store, or from your local auto-parts store or bicycle shop.
Pen Tubes fit ALL V.2 scribers. Straight arms and Arc arms can be used.
Pen tubes do not fit the V.1 ChambersScriber. (Your scriber is engraved either "V.1" or "V.2")
All new scribers come equipped with pen tubes, so if you are buying a V.2 scriber, you do not need to buy these pen tubes.
Pen refills are sold separately. Be sure to add some "refill pens" to your order.
You get 2 pen tubes and 3 caps for $24.50.
