5 new latex fountain pen ink sacs -- #18

Description

Five (5) Latex Rubber Sacs, size 18 (medium)
Brand new sacs, size 18 straight (an easy sliding fit inside barrels up to 9/32" ID, 7.14mm). This is one of the most useful sac sizes, and will fit a wide range of popular full-sized lever-filling and button-filling pens.
These sacs are fresh production for the Pen Sac Company in California, which took over the ink sac production department of White Rubber -- the leading suppliers of sacs to the pen industry from the 1920s through the 1980s. While other materials have their advantages when there are special requirements, for general usage latex sacs remain the best overall choice. Latex sacs are best attached with shellac.
NOTE: Latex sacs are made by dip-molding, so sacs will vary slightly in wall thickness and exterior diameter. Sac sizes are nominal, and indicate that a given sac will easily fit through a hole n/64 inch (1 inch = 25.4 mm) in diameter, "n" being the sac size. For more information on sac choice,
please see the Pen Sac Primer on our website. For more sac sizes and materials, see our

Payment
We are glad to combine shipping charges on multiple purchases, but it is vital that the proper checkout method be used. When buying more than one item, use the Add to Cart button -- NOT the Buy It Now button. View your cart when you are ready to complete the purchase, and if the total shipping charge is incorrect, do NOT pay. Instead, click the Request Total link at the top right and we will send you a corrected invoice.
Terms of Sale
We strongly believe in full and explicit description of any condition problems or flaws, and in very conservative grading. We stand behind our descriptions -- buy with confidence.
