They are perfect and fast delivered, but, mayby they will press and crack the glass. :-) So I have some "leftovers" from lithium-cells I did put onto the clamps at the glass-side. Doing this I can increase the pressure to the clamps without any danger. The leftover I'm using are the centerpad of 0,3mm thick cardboard protecting "rings" (see pictures) to positive end of the lithium-cells before welding those together, but, anything adhesive soft thick paper / cardboard can be used.

Product is used as described. Glass aluminium construction. Good threads. Nice black anodised finish. Suits the purpose of that out they were designed for excellent. I’m glad purchased bought two packs of four :)

Good clips, take it, you will not regret it! Much better than clothespins. Quality norms, screw fastening. Delivery is a simple paper bag, it has a seller's zip package in it. Track tracked

They shipped the package fast and it arrived sooner than what was expected. Great quality fits my ender 3 with glass bed just right though they hold so well I only need 2
