Listings show these sizes as examples: 1" × 3" printable inserts; 2.33" (H) × 3.38" (W) rectangular badges; and 2.31" (H) × 3.31" (W) rectangular badges.
The listings show badge labels made from polyester, polypropylene, and paper.
Printable inserts for reusable magnetic badge systems are non-adhesive peel-off sheets sized to fit the holder. You design and print the insert, peel it from its backing, then slide or place it behind the holder’s lens/cover; the insert can be removed and replaced for reuse.
The listings note compatibility with inkjet printers; some inserts are listed for laser printers, and several items are described as compatible with both inkjet and laser printers.
Pre-printed rectangular badges feature a smooth matte white finish with metallic gold accents (a look standard desktop printers can’t reproduce), while printable badges are described as producing sharp, vibrant prints.
