These modern 100% SILICONE sacs are produced by the injection moulding system.
These are excellent for replacing the sac in your CELLULOID PENS.
The sizing of ink sac's is in units of 64th's of an inch. Therefore a size 16 is 16 / 64th's of an inch in diameter.
In this metric era its 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
