Five (5) Transparent PVC ink sacs, size 14 (small) for Parker 51 Demi (early production), Slimfold, and other slender UK Aerometric Duofolds
If your Parker fountain pen's Pli-Glass sac is no longer transparent or has developed a leak, these newly-made replacement sacs are just the thing. Unlike our full-size 51 sacs, listed separately, these are not ribbed, but they are made of the same material as the Parker originals and should be equally durable. These sacs also fit slender-bodied hard rubber Waterman fountain pens such as the 52½ and 52½V.
PS Though the fit on the sac nipple is tight, these sacs can be used to upgrade vintage Parker metal-bodied squeeze-filling converters, which originally used latex rubber sacs.
NOTE: 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 other eBay listings.
We have over 25 years of experience in vintage pen restoration and tuning. Unless otherwise noted, our pens have been fully reconditioned and are ready to write. Authenticity is guaranteed.
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.
