Description

What Is This Product?

Neodymium Block Magnets are small rectangular magnets for hidden closures. Fit them inside the lid and body of a presentation box, case or acrylic display, and they hold it shut without any visible catch or clasp.

Each magnet is made from N35 grade neodymium with a nickel-plated finish. There are six sizes, from 10 x 5 x 1.5mm to 25 x 10 x 2mm, so you can match the magnet to the thickness of your board or panel. The 20mm sizes and the 25 x 10 x 2mm size are pole-marked, which makes it easier to line up opposite poles during assembly.

Supplied in a pack of 100. The price shown is per pack and depends on the size you choose.


Key Benefits

  • Hidden Fastening
    The magnets sit inside the lid or panel, so the finished box or display stays clean, with no hardware on show.

  • N35 Neodymium
    Neodymium is much stronger than standard ferrite magnets of the same size, so a small block gives a firm, reliable close.

  • Slim Profile
    At 1.5mm or 2mm deep, the blocks fit into thin card, board and acrylic without adding bulk.

  • Six Sizes
    Lengths of 10mm, 20mm and 25mm in two depths let you choose a size to suit the material and the closing strength you need.

  • Pole-Marked Options
    Marked poles on selected sizes take the guesswork out of fitting pairs, which saves time on larger production runs.

  • Nickel-Plated Finish
    The plating protects the neodymium and gives a clean, bright surface.

How It Differs From Neodymium Disc Magnets

Block magnets and Neodymium Disc Magnets are made from the same N35 material and do the same job. The difference is shape. A rectangular block suits slots, routed channels and the straight edges of lids and panels. A round disc suits drilled holes.

  • Block Magnets: Rectangular, from 10 x 5mm to 25 x 10mm, sold in packs of 100.
  • Disc Magnets: Round, for drilled recesses. For peel-and-stick fitting, see Self-Adhesive Neodymium Disc Magnets.

Ideal Applications

Block magnets are used in presentation packaging, retail displays, exhibition stands, shopfitting and promotional print.

  • Magnetic lid closures on promotional and employee onboarding boxes
  • Hidden catches on product cases and gift packaging
  • Removable acrylic panels and graphic fronts on point of sale displays
  • Swappable signage and graphic inserts on display stands
  • Magnetic fixings for sample boxes and swatch cases
