Ceramic Round Magnets With Adhesive Backing

These ceramic round magnets measure 25x4mm and come in a pack of 36 pieces. Each magnet features a durable adhesive backing on one side and a flat ceramic surface on the other. They are designed for organising and decorating in home, office, workshop or hobby environments. The adhesive sticks to plastic, metal, concrete and tiles.

Sustained Holding Performance

Each piece can hold 13.6 oz (386 grams) with a magnetic strength of 2800 Internal GAUSS at Grade 5. The ceramic material offers high resistance to demagnetisation so the magnets do not lose power over time. Oxidation resistant, corrosion and rust resistant properties maintain performance in industrial environments. The adhesive bond remains secure on suitable surfaces under continuous load.

Peel-And-Stick Installation

Installation requires peeling the protective liner and pressing the adhesive side onto a clean, dry surface. The adhesive bonds to plastic, metal, concrete and tiles without tools or fasteners. Common issues occur when surfaces are dusty, oily or uneven, which reduces adhesive contact. The magnets are not suited for buyers who need mechanical fastening or higher shear strength than adhesive alone provides.

Questions about this item

Do the 2800 gauss ceramic magnets lose holding power after months of continuous use on a whiteboard?

The ferrite material has high resistance to demagnetisation, so the 2800 gauss strength remains stable during long-term indoor use.

What surface preparation is needed before sticking the 25 mm adhesive-backed discs to a painted wall?

Clean the surface so it is dry, dust-free and non-porous; the adhesive bonds to plastic, metal, concrete, tiles and similar substrates.

Can these 36 round magnets hold a 386 gram tool on a vertical steel cabinet alongside older flexible magnet strips?

Each disc holds up to 386 grams; the rigid ceramic magnets provide a stronger point grip than flexible strips, so they stay fixed while the older strips may slide.
