Description
Product Overview
Maco OS-288 label sheets are designed for businesses that need dependable, high‑quality mailing labels. Each sheet measures 3‑5/8 × 5‑1/2 in, a standard size that fits a wide range of postage meters and label printers. The product is manufactured by Chartpak Inc., a trusted name in office supplies, and carries the Maco brand reputation for consistency and performance. With a lightweight 4‑ounce package and a compact 4.25 × 0.5 × 7.13 in footprint, the boxes are easy to store on a shelf or in a filing cabinet, making inventory management simple.
The labels feature a permanent adhesive that bonds securely to envelopes, parcels, and other mailing surfaces. Unlike removable or repositionable adhesives, the permanent formula ensures the label stays in place throughout the entire mailing process, even when exposed to moisture or handling. The white, rectangular labels provide a clean canvas for clear address printing, barcode placement, or branding, helping your mail look professional and organized.
Compatibility is a key strength of the OS‑288 series. These labels are fully tested and approved for use in Pitney‑Bowes postage machines model #5675 and #DM3, as well as a broad range of Touchmatic models including #5705, #5460, #4150, and #5830. This cross‑compatibility eliminates the need to purchase separate label types for different equipment, reducing both cost and complexity for multi‑device offices.
Each box contains 160 labels, organized as 40 sheets of four labels each. The packaging includes clear labeling and a sturdy cardboard box that protects the sheets from bending or moisture during shipping. The product’s ASIN B000GOYMHM and model number OS‑288 make it easy to locate in inventory systems, and the item’s best‑seller rank in the postage meter label category reflects its popularity among small‑business and corporate users alike.
Usage
These labels are ideal for any mailing operation that requires reliable, high‑resolution printing. Whether you are preparing bulk invoices, shipping notices, or promotional flyers, the permanent adhesive ensures the label will not peel off during handling or transit. The size fits standard envelope windows, allowing addresses to be visible without additional window stickers.
In a typical office setting, users load a single sheet into the postage meter, print the required information, and then apply the label to the envelope or package. The adhesive activates instantly, so there is no waiting time for the label to set. For businesses that process hundreds of pieces of mail per day, this speed translates into measurable productivity gains.
Beyond traditional office use, the OS‑288 labels work well in call‑center environments, fulfillment centers, and even home‑based e‑commerce operations. Their durability makes them suitable for shipping heavier parcels, while the clear white background supports high‑contrast printing for barcodes and QR codes, which are increasingly used for tracking and verification.

FAQ
Can these labels be used with other brands of postage meters?
While the OS‑288 series is specifically tested for Pitney‑Bowes and Touchmatic machines, the dimensions and adhesive properties are compatible with many other brands that accept standard 3‑5/8 × 5‑1/2 in labels. We recommend a short test run to confirm performance before full‑scale use.
What is the difference between permanent and removable adhesive?
Permanent adhesive is formulated to create a strong bond that does not lift or shift, even when exposed to moisture or handling. Removable adhesive is designed for temporary placement and can be peeled off without leaving residue, which is not ideal for mailing where the label must stay in place throughout delivery.
How many labels are in each box and how are they packaged?
Each box contains 160 labels, organized as 40 sheets of four labels each. The sheets are stacked in a sturdy cardboard box that protects them from bending and moisture during shipping and storage.
Are the labels recyclable?
The label substrate is made from recyclable paper material. While the permanent adhesive is designed for durability, the paper can be recycled in most municipal recycling programs after the adhesive has been removed or when the label is no longer needed.
