These tweezers 2.5 cm long are super practical. The pot is always open on set that we can use at will. Their surface where the pressure has been very small and yet they cling super strong. The small "teeth" on the line pressure well maintain the pinched object. No internal spring like clothespins but a folded metal strip, which gives them, I think, a good life. Useful sewing, groceries, or for paperwork ... more searching, simply dip into the pot!
