These clamps were high on a letter to Santa. I hesitated with another model, a priori more versatile, but I decided for this one because of the price per unit. Upon receipt of the package, there was only one clip, instead of the 12 announced. Phone call to customer service, which checks the product and re-create myself once an order. As I did almost all my shopping at Amazon, she lived the rest is shipped. Upon opening the package, in the middle of the boxes, there is a single clip that wanders, in bulk. Back to customer service, reverification detail (packaging: 12) .... Returning an order, with a note, polite, telling me to keep the 2 clamps received. Arrival of a medium sized cardboard, and there ... Placed in the middle of the paper, a single clip. There, I give up. In addition, it is too late for a Plan B. Gift I much control, long time on Amazon, I had never encountered this problem.
