Review on Accurate Uxcell Metric Thickness Stainless Measuring Tool: A Precise Solution by Brandon Show

Received last weekend and taken out of box on Monday. Today is Friday. They weren't rusty when I took them out of the box. I haven't wiped them, dipped them in anything, or done anything to them other than taking them out of the box and using them to align the printer once. They were kept in an office next to a 3D printer, not in a swamp. However, in less than a week they rust and are virtually unusable for their intended purpose.
