What makes these magnets stand out
- Heavy-duty adhesive + ferrite strength: One side is sticky (pre-applied adhesive), the other side is a flat ceramic magnet. Stick them to non-magnetic surfaces to create a magnetic spot anywhere—tile backsplash, plastic bins, painted drywall, glass, or concrete.
- Grade 5 ferrite with 2800 Gauss: Ceramic magnets aren’t quite as punchy as neodymium by size, but Grade 5 ferrite delivers reliable, stable pull for everyday tasks while resisting corrosion naturally.
- Real-world hold: Rated up to 13.6 oz per magnet. That’s enough for paper stacks, cables, lightweight hand tools, small kitchen utensils, and many craft applications. Note: Hold depends on surface thickness, smoothness, direction of pull, and how long the adhesive has cured.
- Corrosion and rust resistant: Ferrite ceramic won’t rust, so these are great for damp environments like bathrooms, basements, and garages.
- Versatile, ready to use: No screws, no separate pads to cut. Peel, press, and you’re done.
What’s in the box
- 18 round ceramic magnets with pre-applied adhesive backing
Real-world use cases
- Kitchen and pantry: Create a magnetic zone on a tile backsplash for metal hooks, timers, bottle openers, or spice containers with steel lids. Label shelves using magnetic clips.
- Office and classroom: Turn walls, cabinets, or doors into magnetic presentation areas. Stick to plastic or glass and use with magnetic pins or clips for notes, calendars, and schedules.
- Workshop and garage: Add magnets to wood, plastic, or concrete surfaces to hold small steel tools, bit holders, measuring tapes, or to mount a removable parts tray.
- RVs and apartments: Rent-friendly storage. Build a magnetic message center without drilling. Perfect for lightweight metal hooks and clips.
- Crafts and DIY: Magnetize the backs of 3D prints, photo frames, or signage. Make your own magnetic knife guards or closures for boxes and portfolio cases.
Performance notes and limitations
- Pull vs shear: The 13.6 oz spec typically refers to direct “pull” from thick steel. Sideways “shear” loads (sliding) can lower practical holding power. For heavier items, use two or more magnets.
- Surface prep matters: Adhesive strength improves with clean, dry, non-porous surfaces. Rough, dusty, or oily walls reduce grip.
- Curing time: Press firmly for 30–60 seconds. Let adhesive cure 24 hours before loading to reach full bond strength.
- Temperature/humidity: High heat and moisture can weaken many adhesives over time. For long-term outdoor use, consider covering edges or using additional adhesive rated for exterior conditions.
Installation tips
- Clean the surface with isopropyl alcohol and let dry completely.
- Test-fit placement first. Mark lightly if needed.
- Peel the liner, press magnet firmly for 30–60 seconds with steady pressure.
- Rotate magnets so they don’t collide hard with each other—ceramic is brittle if snapped together.
- Wait 24 hours before loading for best results.
How strong are they?
- Paper and photos on a fridge/whiteboard: 1 magnet is plenty; add clips for heavier stacks.
- Small steel tools (e.g., 6–10 oz): 1 magnet can work on clean, flat steel; 2–3 magnets recommended for better shear resistance.
- Kitchen utensils: Works well for metal bottle openers, peelers, or lightweight tongs. For knives, test carefully and consider multiple magnets or a dedicated knife strip for safety.
Build quality and durability
- Ferrite ceramic core: Stable, resists demagnetization better than many alternatives, and naturally corrosion-resistant.
- Adhesive pad: Strong peel-and-stick convenience. Because the adhesive is doing half the job, proper prep and cure are crucial.
- Brittle by nature: Ceramic magnets can chip if dropped or slammed together. Handle with care and keep out of reach of children.
Who they’re best for
- DIYers needing magnetic zones on non-magnetic surfaces
- Teachers, organizers, and office pros managing visual boards
- Crafters making magnetic signage, closures, and frames
- Renters and RV owners who want no-drill storage solutions
Who might want something else
- Heavy-duty, compact strength needs: Consider neodymium magnets for higher pull in a smaller footprint (but expect more corrosion risk and careful handling).
- Wet, high-vibration environments with heavy loads: Mechanical fasteners or screw-in magnetic bases are safer.
- Fully removable/repositionable solutions: Use command strips with magnetic plates or hook magnets on steel surfaces.
Pros
- Strong, Grade 5 ferrite magnets with 2800 internal Gauss
- Pre-applied adhesive—no extra glues or hardware
- Rust/corrosion-resistant; suitable for kitchens, garages, bathrooms
- Versatile use across home, office, classroom, workshop, RV
- Easy installation; sticks to tile, plastic, concrete, metal, glass
- 18-pack provides excellent value and flexibility
Cons
- Ceramic is brittle—avoid impacts and snapping magnets together
- Adhesive strength depends on surface prep and cure time
- Lower strength per size than neodymium; may need multiples for heavier items
Safety notes
- Keep away from small children and pets—magnets can be dangerous if swallowed.
- If you or someone nearby uses a pacemaker or similar device, avoid placing magnets close to the device area.
- Don’t use on high-heat surfaces; magnets can demagnetize at elevated temperatures.
Value and verdict
For the price and flexibility, this 18-pack of adhesive-backed ceramic discs is a smart buy for anyone who wants to add magnetic functionality to non-magnetic surfaces—fast. The adhesive is convenient, the Grade 5 ferrite is stable and rust-resistant, and the 1″ x 0.15″ size strikes a useful balance between footprint and holding power. Prep the surface well, allow the adhesive to cure, and use multiple magnets for heavier items—you’ll get reliable, tidy organization with no drilling required.
