Pure cotton material: The front and back of the quilt clips are made of comfortable cotton fabric, skin-friendly and soft to the touch. Even in cold winter, the material feels warm and allows for a comfortable night's sleep. Not easy to fall: The quilt clip securely holds quilts, sheets, sateen sheets, mattress pads, and blankets, helping to prevent shifting, slipping, and wrinkles, keeping the bedding neat and tidy. Designed with strong compression and tensile strength, it stays 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 secure by inserting the plastic nail into the round hole of the quilt clip. The clip features a button design for one-touch release, requires no needles, and provides firm fixation for undisturbed 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 functionality, it serves as a stylish bed accessory with a lightweight, chic appearance, smooth rounded edges, and a thornless, skin-friendly surface.
