About our mailing supplies

SuppliesForMailers.com is the mailing-supply division of All For Mailers, Inc. — a veteran-owned, BBB A+ accredited mailing-equipment dealer that has served production mailers, lettershops & in-plant mailrooms since 1995. We carry the consumables and parts that keep addressing printers, wafer sealers and tabbers, envelope sealers and folder-inserters running every day.

Our addressing ink line covers HP C8842A Versatile Black, Collins Reliable H, Rena EasyInk for the Quadient AS-Series, our own SFM 42 remanufactured C8842A at $17 or less, plus MACH 5 & MemJet inks, Formax ColorMax for full-color envelope printing on the Quadient MACH 7, and Formax AP inks. SFM-branded inks are stocked in Pennsylvania and California for faster nationwide delivery.

Our wafer seals and postal tabs meet USPS DMM requirements and ship in 1″, 1.5″ and 2″ diameters in translucent, white and clear, fitting Accufast KT, KT-2, QT, Rena T-250 through XPS Pro Tab, Astro 9600/9900, Buskro, Kirk Rudy, ProFold, Secap Jet1 and Printstream II, Pitney Bowes W350, and Staplex tabbers. 5,000-per-roll small cases ship from our Pennsylvania warehouse; large 40,000-per-roll bulk cases ship from our North Carolina warehouse.

We also carry postage meter ink, ribbons and tapes for Pitney Bowes, Quadient, Hasler and Francotyp Postalia.

For parts, we stock the most-common replacement items — feed rollers, separator tips, sensors, belts — in our Pennsylvania warehouse. Less-common and specialty parts drop-ship directly from our manufacturer partners: Docufeed in Washington state, plus Formax, Quadient, Walco, Straight Shooter and Astro. There are simply too many production-mailing parts for any one supplier to stock everything — our multi-warehouse network is how we get you what you need without delay.

Frequently asked questions

Where do you ship from?
We ship from multiple US locations to get your order to you faster. Our main warehouse in Pennsylvania stocks SFM inks, 5,000-per-roll wafer seals, and the most-common replacement parts. We also stock SFM inks in California for west-coast customers, and large bulk cases of postal tabs and wafer seals in North Carolina. Specialty parts drop-ship directly from manufacturer warehouses including Docufeed (Washington), Formax, Quadient, Walco, Straight Shooter and Astro.
What ink does the Quadient AS-Series addressing printer use?
The AS-450, AS-650 and AS-850 use Rena EasyInk cartridges, which are mechanically identical to HP C8842A Versatile Black. Our SFM 42 and Rena EasyInk drop in directly.
Are your wafer seals USPS-compliant?
Yes. All of our wafer seals and postal tabs meet or exceed USPS DMM 201.3.14 booklet and folded self-mailer tabbing requirements.
Can I substitute your sealing solution for Pitney Bowes EZ Seal?
Yes — our sealing solution matches EZ Seal and Quadient Sure-Seal performance: same wetting, same adhesive activation, no residue. Most customers cut their sealing-fluid cost in half.
Do you stock parts for my machine?
We stock the most-common replacement parts in Pennsylvania. For specialty parts, we work directly with manufacturer warehouses — Docufeed (WA), Formax, Quadient, Walco, Straight Shooter, Astro — to drop-ship the exact part you need. There are too many production-mailing parts for any one supplier to stock everything; our network is built so you don't have to chase a part across vendors.
Do you offer free samples?
Yes. Free sample rolls of wafer seals are available — call 1-866-430-2874 or use our sample-request form.
