Round Magnetic Whiteboard Pins 6 Color Assorted Set (1.5 cm / 2cm / 3cm / 4cm)

Six punchy colors circle around one smooth dome shape, built as sturdy colorful magnet buttons that snap onto any steel surface without fuss🧲. The rounded ABS cap sits comfortably under a fingertip, so grabbing and repositioning a note takes barely a second🎨. Underneath that glossy shell, a compact magnet locks papers, photos, or charts flat against a memo board🗂️, keeping edges from curling or slipping mid-meeting.

Reaching across four sizes, from a fingertip-sized 15mm dot to a chunky 40mm disc, these round magnetic pins adapt to whatever gets pinned up🧷 — thin memos need a small anchor, while thick folders or maps call for the bigger cap🖼️. Mixing sizes within one whiteboard magnet set also makes it easy to separate categories at a glance, no labeling required🔧.

Because there's no metal point involved, little fingers can help organize a family calendar or class chart without any poke risk🪄. Color-coding tasks with these magnetic memo holders turns a plain board into a quick-read planner🧩, and popping a magnet off leaves zero residue or dents behind📎.

Q&A

Will magnetic buttons scratch a whiteboard surface?

Smooth-capped magnets glide on and off without any sharp point touching the board, so a typical whiteboard surface stays scratch-free. The real risk comes from sliding a magnet sideways under pressure, which can wear down coated or painted boards over time. Lifting straight up instead of dragging keeps both the board and the magnet's finish looking new for longer.

How many sheets of paper can a small magnet actually hold in place?

Holding power depends on magnet size and board thickness, not diameter alone. A fingertip-sized magnet typically secures one or two sheets, while a larger disc can pin down a small stack or a folded map. Thicker boards with less metal backing reduce grip, so heavier items usually need two magnets spaced apart instead of one.

What's the difference between a ferrite magnet and a neodymium one?

Ferrite, or ceramic, magnets are affordable, rust-resistant, and plenty strong for everyday paper and light folders. Neodymium magnets pack far more pull force into a smaller size, which suits heavy files or metal tools, but cost more and can chip if dropped. For everyday board organizing, ferrite strikes a practical balance between price and grip.
