This four-pack supplies PB SL-870-1 red fluorescent ink cartridges built for the SendPro Mailstation (CSD1) postage meter. Each cartridge is USPS-certified and manufactured to meet OEM performance standards. The set provides a low-cost alternative that does not void the meter warranty.

Replaces OEM 870-1 Supply

The cartridges directly replace the original Pitney Bowes 870-1 ink supply for the same meter model. Buyers who want more storage or a different ink colour will not be served by this pack. The switch is worth it when a compatible, warranty-safe option at a lower price is required.
