This is a multi-clip strap from agnès b. It's a convenient item that can be used as a bib by attaching a hand towel to the clips on both ends. To open the clip, press the clip with your thumb and index finger, and then push down the ring at the base of the clip. The clip will open approximately 9mm. Please note that there are fine scratches, especially on the back of the clip, and the strap part of the string has some loose threads and wrinkles, as shown in the photos. Thank you.
