The shell of an electronic handheld device is adapted for easy and repeated—even frequent—assembly with and disassembly from the electronics, and the shell is washable, preferably in a dishwasher. Preferably, the shell comprises a plurality of parts that can be easily and repeatedly assembled and disassembled by hand without use of tools. For example, the parts of a telephone handset shell are made to be easily snapped together around, and unsnapped from, the handset's electronics, thereby enabling the shells of the handsets of telephones to be washed to have this function performed by unskilled personnel.
