The Nokia 8210 was, at the time of its release in 1999, the smallest, lightest Nokia mobile phone on the market,[citation neeed] thus its selling point was based on its design and customization, with removable Xpress-on covers. Six differently coloured Xpress-on covers are available, as well as many third party ones. Unfortunately one of the design faults of the Nokia "82XX" series was that many developed "screen fade" which is a condition where figures on the display would eventually be so dim that it was impossible to read the display.
