Package Included: You will receive 16 sets of duvet cover clips, including 16 mushroom buttons and 16 spikes. The spikes are suitable for thick fabrics such as spring, autumn, and winter quilts, cushions, and seat cushions. Simple to use: Thread the needle through the quilt, then insert the spike into the round hole on the other end to secure. To remove, simply press the button to unlock; it is easy to detach. Unique Design: The duvet clamp features a one-touch unlock mechanism. The spike tips easily penetrate multiple layers of fabric. The inner clip material is high-quality aluminum, which enhances safety and reduces the risk of puncture. The semi-circular mushroom shape effectively holds the duvet in place and adds a subtle decorative element. Material: Mushroom buttons and spikes have a cotton-like finish, offering a soft texture that feels comfortable to the touch. The base is made of durable, wear-resistant ABS material. Lightweight and Safe: These lightweight fasteners eliminate the need for bulky clips or magnets that may damage or weigh down your quilt. Ideal for quilts, cushions, curtains, sofa covers, and pillowcases, they provide a secure hold without loosening easily. Simple and elegant, these clips offer convenience and improve your everyday experience.
