I use clear plastic wrap, which I bought in Rymans at the moment. That seems to work pretty well.
Soap Kitchen do both clear cellophane wrap and some funky coloured versions.
https://www.soapkitchenonline.co.uk/aca ... plies.html I have used their transparent gold dots wrap before, which looked pretty when I was wrapping things at Christmas time. Soap Basics do shiny clear wrap too.
http://www.soapbasics.com/contents/en-uk/d54.html Soap Basics have a minimum order of £20, though for most things I find them to be slightly cheaper (though bear in mind the prices you see are before VAT, which they add at the end, so you can end up spending more than you expect!) Both companies have been pretty prompt with delivery when I've ordered from them.
The cellophane wrap I use is a bit more substantial than cling film. Cling film will probably work, but probably is harder work and doesn't look as pretty.
