Hy-ko MM-29L 3 Inch Reflective Mailbox Letters 29 Pack

Product Description

The HY-KO MM-29L is a pack of 3-inch self-adhesive letters featuring black characters printed on a reflective background. The reflective surface improves visibility in low-light conditions, making these letters well suited for mailbox identification, address markers, and similar outdoor applications. Each package contains 29 total characters, giving installers enough to complete a full address or labeling job in a single purchase. The lightweight construction keeps the package at approximately 0.17 pounds, making it easy to handle and ship. These letters are commonly installed by property owners, contractors, and sign-shop technicians as a quick, no-tool address marking solution.

These reflective letters are designed for residential and light commercial use. Common applications include mailbox numbering, house number display, crafts, storage bin labeling, and general property identification. The reflective backing adds visibility for nighttime readability, which is particularly useful for emergency services locating an address. The 3-inch character height meets many local ordinances for minimum address numeral size on residential mailboxes and structures.
