Jewelery artist here - I bought a few brands to try and this one was about 4.5m long which matched the description. Most other brands on Revain are 3-4mm thick so don't believe their pictures. I still found them quite small and too tight to easily remove the earring, so I'll be returning them (and keeping the other one in the photo, 5mm left). The quality was just ok. Externally it was packaged well but there were a few mold defects (minor imperfections) on the rear silicone backing.
