The best magnets for polymer clay fridge magnets are small disc magnets that can fit inside or attach to a finished clay design. The Caturledas 5 x 2 mm set is best for making many compact pieces, while the DIYMAG 8 x 3 mm set suits projects with room for a larger magnet. Linlinzz options offer different quantities and dimensions. Check each magnet’s size against the clay design before buying, and plan how it will be secured.

|---|---|---|
| Caturledas 250-Pack | Batch-making small magnets | 5 x 2 mm |
| Linlinzz 60-Pack | Compact, low-profile projects | 5 x 2.8 mm |
| Linlinzz 40-Pack | A slightly larger disc | 6 x 2.8 mm |
| DIYMAG 100-Pack | General craft use and storage | 8 x 3 mm |
| DIYMAG 5-Size Set | Projects with varied dimensions | 6–15 mm diameters |
Caturledas 250-Pack, 5 x 2 mm
Best for: makers producing many small polymer clay magnets. This set includes 250 round neodymium magnets, each measuring 5 x 2 mm. Their small diameter makes them a practical option for miniatures and compact designs where a broad magnet would take up too much space.
The magnets have a triple-layer Ni+Cu+Ni coating, which the product description identifies as smooth, shiny, scratch-resistant, and rustproof. The large quantity is useful for repeated craft projects or keeping spare magnets on hand.
Limitation: At 5 mm across, these are tiny components. Measure the available space in the clay piece and handle and store them carefully, especially around children and pets.
Linlinzz 60-Pack, 5 x 2.8 mm
Best for: compact designs that need a thin disc and a moderate pack size. Each of the 60 round magnets measures 5 x 2.8 mm and has a nickel coating. The listed dimensions make this option slightly thicker than the Caturledas magnets while keeping the same small diameter.
The product is also described for card making, craft projects, and model making. Its small shape can help keep a magnet from covering a large area behind a finished clay piece.
Limitation: The product description does not provide a specific holding-strength figure for a polymer clay magnet. Test the finished piece on the intended metal surface rather than assuming it will hold a particular weight.
Linlinzz 40-Pack, 6 x 2.8 mm
Best for: makers who want a little more magnet surface than a 5 mm disc provides. This 40-pack uses nickel-coated round magnets measuring 6 x 2.8 mm. It is a useful middle-ground size for clay pieces with enough room for a slightly wider magnet.
The listed uses include card making, craft projects, and model making. The product description also says the small magnets are designed not to cover up displayed items when used on a board or refrigerator.
Limitation: This set has fewer pieces than the 60- and 250-count options. Choose it if the 6 mm diameter fits your design; it may be too wide for very small clay shapes.
DIYMAG 100-Pack, 8 x 3 mm
Best for: medium-sized clay designs with space for an 8 mm disc. This set contains 100 magnets with brushed nickel finishing. The product description highlights resistance to demagnetization, corrosion, and oxidation, as well as a smooth finish intended to help avoid scratches on surfaces.
The 8 x 3 mm size is larger than the compact options above, which may make it easier to position in a broader design. The included storage case is useful for keeping a batch of small components together between craft sessions.
Limitation: These discs need more room than 5 or 6 mm magnets. Avoid this size if it would leave too little clay around the embedded magnet or interfere with the design.
DIYMAG 60-Pack, Five Magnet Sizes
Best for: crafters who want to compare several disc diameters before settling on one. This set includes 12 magnets in each of five sizes: 6, 8, 10, 12, and 15 mm, all listed as 2 mm thick. The assortment lets makers match magnet diameter to different clay shapes or project sizes.
The product is described for DIY projects, arts and crafts, whiteboards, and other magnetic uses. The range is especially useful when a single fixed size would not suit every design.
Limitation: The set includes no 5 mm option, and its largest discs may not fit small clay pieces. Check the diameter of each design before choosing a size.
Buying Guide: Choosing Magnets for Polymer Clay
What magnet size fits the clay design?
Compare both diameter and thickness with the space available in the finished piece. A 5 mm disc can suit a miniature design, while an 8 mm or larger disc needs more room. Leave enough clay around an embedded magnet so the design can fully conceal it without becoming too thin or fragile.
Should you choose a single size or an assortment?
A single-size pack is a straightforward choice for repeating one design. A mixed-size set is better when you are still deciding what works across several shapes. Consider pack quantity as well: larger sets are useful for batch production, while smaller packs may be enough for occasional projects.
How should the magnet be attached?
Plan the attachment method as part of the design. A magnet can be embedded or attached to the back of a finished piece, but the product details here do not specify a clay-compatible adhesive or baking method. Follow the clay maker’s instructions and the magnet product’s guidance; do not assume every magnet is suitable for baking.
How can you check the finished hold?
Test a completed magnet on the intended refrigerator or other metal surface. The weight, shape, and contact area of the clay design affect how it sits and holds. Product descriptions that call a magnet strong do not establish how much a specific finished craft will support.
Frequently Asked Questions
What size magnet is best for polymer clay fridge magnets?
There is no single best size for every design. Small 5–6 mm discs suit compact pieces, while larger designs may accommodate 8 mm or wider magnets. Match the disc to the available space.
Can I bake a magnet inside polymer clay?
The supplied product information does not confirm that these magnets are safe for baking. Check the clay and magnet manufacturers’ instructions before exposing a magnet to oven heat.
Are all the listed magnets the same thickness?
No. The listed options range from 2 mm thick to 3 mm thick, so check thickness as well as diameter when planning an embedded magnet.
Which option is best for making many small magnets?
The Caturledas set provides 250 magnets measuring 5 x 2 mm, making it the largest listed quantity and one of the smallest specified sizes.
Do polymer clay magnets need to be tested after assembly?
Yes. Test each finished piece on the intended surface because the final hold depends on the magnet, clay piece, and contact with the metal.
