Pure cotton material: The front and back of the quilt clips are made of comfortable cotton fabric, offering a soft and skin-friendly touch. Even in cold winter, the material feels warm to the touch, helping you stay cozy throughout the night. Not Easy to Fall: The quilt clip securely fastens quilts, sheets, sateen sheets, mattress pads, and blankets, preventing shifting, slipping, and wrinkles, keeping your bedding neat and tidy. Designed with strong compression and tensile strength, it stays firmly in place without deformation and fits quilts up to 15 cm thick. Easy Installation: Simply insert the pin through the duvet cover to create a hole, then attach the plastic nail into the round hole of the duvet clip to secure. The clip features a button design for one-touch release, requiring no needles, ensuring firm fixation and comfortable sleep. Safety and Style: The mushroom-shaped duvet holder has a non-magnetic design with no radiation, making it safe for use by pregnant women. Beyond function, it serves as a stylish bed accessory with a lightweight, chic design, smooth rounded edges, and a thorn-free, skin-friendly surface.
