No, our magnets use strong, industrial-grade adhesive that firmly sticks to most smooth surfaces. For best results, clean and dry the surface before applying and press firmly for 30 seconds. How strong are these magnets? These are soft, flexible magnets designed for lightweight items like photos, notes, or small decorations. They are not intended for heavy-duty use. Will these magnets work on all surfaces? They stick best to smooth, flat surfaces. Avoid rough or porous surfaces, as they may reduce adhesion. Are these magnets difficult to separate from each other? They can stick together tightly, but you can easily separate them by sliding them apart instead of pulling straight. Can I cut these magnets into smaller pieces? Yes! These flexible magnets can be easily cut with scissors to fit your exact needs. Just make sure to cut evenly for best results.
