Heavy Duty and Antislip This bed sheet holders set is made from strength ABS+PP for durability and longevity. The frosted surface increases friction for a secure grip. The innovative Vshaped bite structure, combined with widened contact surfaces, delivers an 80% increase in sheet movement resistance. Embedded antislip teeth, plus an external elastic band inserted into the slot, provide a double guarantee for a strong grip. Suitable for a variety of fabrics including cotton, linen, Tencel, coral fleece, and more. Minimalist Installation Patented slot design enables a simple threestep operation without tools or complex steps: 1. Hold the Vshaped fixator at the edge of the mattress. 2. Cover the bed sheet with the fixator, insert the elastic band into the slot to fix the bed sheet. 3. Pull down, organize the bed sheet, and press it under the fixator to keep sheets firm and tight. Daily use does not require dismantling the mattress and supports unlimited reuse.
