Yet another USB flash drive in leather flavour

Step 3 Find out that glue won't hold shiny surfaces.

Against what is advertised on the packaging, the impact adhesive wouldn't hold the shiny steel surface of the USB flash drive. I had to scratch hatches on the surface to roughen it up. Use a sharp object, i.e. a utility knife for that.

Clean the surface with rubbing alcohol (isopropyl alcohol) to clean it from oil and grease. Re-apply the glue on the drive surface.
