Designed with high-quality adhesive and stainless steel backing, this magnetic curtain closure offers a secure and durable solution for keeping your curtains firmly closed. The adhesive ensures long-lasting attachment to your window frame without falling off, making it perfect for blackout curtains. Featuring triple neodymium magnets, this closure delivers three times the magnetic force of standard models, ensuring even heavy-duty curtains close perfectly. It effectively blocks light to create a flawless blackout environment, enhancing sleep, relaxation, and privacy. The windproof design eliminates the need for traditional pins or clips that can puncture and damage curtain fabric. Instead, advanced magnet technology keeps curtains securely in place, even in strong wind conditions, while protecting the fabric for long-term use. Installation is quick and hassle-free — simply clean the window frame, peel off the adhesive backing, press the stainless steel plate onto the frame, and wait 24 hours before attaching the magnets. No tools are required, making setup simple and convenient. The package includes 12 pairs of magnetic curtain closures, with 2 pieces per pair: one stainless steel front plate and one plastic strong magnetic back plate. For optimal performance, attach the metal plate to the window frame rather than the glass, as sunlight and heat may weaken the adhesive. Please handle the magnets with care, as they are fragile. To reduce magnetic force for easier removal, gently rotate the magnets during detachment.
