A4 self adhesive flexible rubber magnet sheet is a standard A4 size multi-functional soft magnetic accessory. It replaces traditional rigid magnets, ordinary double-sided tape and disposable stickers, solving common problems such as surface damage, weak viscosity, limited shaping and stubborn residual glue, balancing easy installation, stable adhesion and long-term cost performance.
🧴Full Coverage Uniform Strong Adhesive
Equipped with full area pressure sensitive strong adhesive, the sheet features even and full glue coating with balanced adhesion. It fits firmly on flat surfaces including metal, glass, wood, plastic and acrylic, resisting warping, bulging and degumming for long-term stable indoor fixing.
✂️Flexible & Customizable DIY Material
Made of premium eco-friendly flexible rubber magnet, it is soft, bendable and rollable for flat and slightly curved surface fitting. It can be freely cut into any shapes and sizes with ordinary scissors, leaving neat crack free edges without affecting magnetic performance.
🧲Stable Permanent Magnetic Force
Adopting permanent magnet technology, the whole sheet delivers even and gentle magnetism without loosening. It never demagnetizes or weakens after long-term repeated use. The ultra-thin lightweight design saves space and avoids damaging light materials for precise fixing and display.
🛡️Drill Free Repositionable & Residue Saving
No drilling, screws or extra glue required for quick peel-and-stick installation. It supports free disassembly and repositioning without damaging decorated walls, finished furniture, teaching tools and display boards, realizing reusable installation.
☔Weather & Aging Resistance for Wide Usage
Upgraded with anti-aging and moisture proof treatment, both the magnet base and adhesive feature excellent dust proof, wear resistant and anti-yellowing performance. It maintains stable performance without deformation for long term cyclic use in home, office, teaching, commercial and light industrial scenarios.
Stable Magnetism：resistant to oil, solvents, and moderate heat; suitable for factory environments
