CHUNNIAO Magnetic Whiteboard Tape, 1/2-Inch Black Strips, 50 Ft Roll

Some board layouts need fixed lines, others benefit from boundaries that can be moved as plans change. CHUNNIAO magnetic tape creates flexible sections on magnetic whiteboards and other metal surfaces.

The black strips form visible grid lines for calendars, timelines, charts, and planning boards. Their magnetic, non-adhesive design lets you reposition them without leaving adhesive residue.

A 50-foot roll gives you material for custom layouts, and the tape can be cut with regular scissors to suit the lines you want to create.

Tech summary

• Type: Magnetic whiteboard tape
• Color: Black
• Strip width: 1/2 in
• Length: 50 ft
• Format: Roll
• Adhesive: Non-adhesive magnetic strips

The narrow strips are suited to making fine lines that divide a board into useful sections without turning the layout into a solid block. Use them to mark rows and columns, separate calendar days, or outline areas for tasks and notes. Because the strips can be moved, a layout can be adjusted when the information or planning format changes.

What it works with

The tape is intended for magnetic whiteboards and other metal surfaces, including metal cabinets, steel lockers, and refrigerators. It works by magnetic contact rather than a sticky backing, so the surface needs to be metal for the strips to hold. This makes it a practical choice when you want temporary, repositionable lines instead of a permanently adhered grid.

For a classroom board, for example, cut strips to create a timeline or divide a planning area into columns. The same roll can also help organize a metal cabinet or locker with visual sections. Cut each strip with regular scissors, then arrange the lines on the surface to suit the layout.

Buyers praise the tape’s quality, while some express concerns about how well it stays in place. Its non-adhesive construction is an important part of how it is designed to work: the strips rely on magnetic contact with a compatible metal surface rather than adhesive.

Best use cases

This roll is a useful fit for teachers building flexible classroom grids, teams organizing a magnetic planning board, or anyone marking sections on a metal surface. It can create calendars, timelines, charts, and other layouts where clear divisions make information easier to scan. Compared with fixed markings, magnetic strips offer a layout that can be rearranged, compared with adhesive borders, they avoid sticking to the board. The 1/2-inch width is suited to fine-line sectioning, while the roll format lets you cut the lengths needed for a particular design.
