To find out what size sac your pen requires, measure the diameter of the sac peg as shown below. Use this measurement to find the size of sac.

These modern 100% SILICONE sacs are produced by the injection moulding system.

These are excellent for replacing the sac in your CELLULOID PENS.

When Replacing old ink sac with the SILICONE Versions
you may wish to use a stronger adhesive.
AMBERSIL is ideal for this.

Available in a 75 ml resealable tube with dispensing nozzle.

To apply use as you would Shellac.
Apply a small amount around the sac peg, fit the sac and allow to dry for 24 hours before 
fitting and testing.

 

In this metric era it's a little difficult to measure in that format.

The table below of sac sizes has been converted to the nearest metric mm equivalent.


Available in the following sizes.


Size 14 Fits a sac peg of 5.5 mm

Size 15 Fits a sac peg of 5.9 mm 

Size 17 Fits a sac peg of 6.7 mm  

Size 18 Fits a sac peg of 7.1 mm


If the size of the sac peg fall between two sizes choose the smaller size sac.
