Unique Design:: The clip has a one-click release design. The tip of the nail can easily penetrate through multiple layers of tissue. The inner material of the clip is made of high quality aluminum, which is safer to use and greatly reduces the risk of punctures. The semi-circle mushroom shape can not only prevent the quilt from shifting well, but also beautify the quilt as a beautiful decoration. Light Safe: : With these light and small fixing clips, you don't need to use bulky clips or bulky magnets, which could damage the duvet or make it heavy. As practical tools for quilts, cushions, curtains, sofa covers and pillowcases, they are not easily loosened. Simple and elegant, these little things will save your time or effort and bring you a good experience. Simple to use:: You just need to pass the needle through the quilt and put the nail through the round hole at the other end to secure it. When you want to remove it, you can press the button to unlock it directly, which is very easy to remove. High quality materials:: Buttons and mushroom-shaped studs have a cotton surface. The texture is soft and you will not feel cold to the touch of the body. The ABS material at the bottom is strong, wear-resistant and durable. Package list:: You will receive 16 sets of duvet cover clips: 16 x mushroom buttons, 16 x long nails, 16 x plastic nails. Long nails can be applied to thick fabrics such as spring, autumn and winter quilts, back cushions and seat cushions.
