【GIGASTONE】 Z90 128GB 2-Pack USB 3.2 Gen1 Flash Drive, Mini Fit Metal Waterproof Compact Pen Drive, Reliable Performance Thumb Drive, USB 2.0/3.0/3.1 Interface Compatible

This USB memory stick is compact, fast and works well. It is s little larger than my old one and the key ring opening is not as large, so it is not movable on my keychain. Other than that it is the smallest physical size I could find in a 126GB capacity.
