High-quality material & quality: Our high-quality magnetic plates with strong adhesive surface are anisotropically magnetized (direction of magnetization exclusively in the given direction -> adhesive force is higher) & have a thickness of 1.2 mm, which is stronger than many comparable offers. Due to the stronger magnetization & the greater thickness, these flexible, adjustable magnetic-strips have an optimized magnetic strength & are very versatile! Size & Specification: The magnet plate set consists of anisotropically magnetized iron oxide, rubber & an adhesive tape attached to the back. The magnet plates have different sizes (see graphic for details!) & a thickness of 1.2 mm. The pre-punched, adhesive rubber magnets are distributed on two sheets. The magnetic stickers have a magnetic field of approx. 510 Gs & a magnetic holding force of approx. 70-80 g/cm2, depending on the type of application (horizontal or vertical). Scope of delivery: You will receive 58 magnetic-plates of different sizes (see graphic for details!) divided into two sheets (2 x 29 pieces). Each sheet with pre-punched rubber magnet plates contains 29 sticking magnets. Versatile use: Our magnetic strips are suitable for school lessons, workshops, presentations, handicraft work & for the office. The magnet-plates can be used quickly, are easy to remove, can easily be cut to the right size with scissors & stick reliably. With our flexible rubber magnets with an adhesive surface, images, posters, paper & cardboard can be magnetized quickly & then hold on to metal surfaces, steel enamel boards & info boards. Brand quality from Magnetastico: Like all other magnetic Magnetastico products, these anisotropic magnetic-stickers are high-quality everyday companions with an almost unlimited range of applications! Our rubber adhesive magnets are anisotropic, have a thickness of 1.2 mm & are therefore significantly stronger than usual magnets. Also, several layers of laminated paper, pictures, posters, signs & postcards hold without problems. For heavier items simply attach several rubber magnets!
