Can anyone give me any information on one piece and two piece probes for an electrical epilation project as ive tried websites and so far got nothing 
What kind of info are you after? As you’re in the UK you should try emailing elaine at sterex (addy is on the sterex website), she will give you all the info you need but you have to say what it is you want to know.One piece are fairly rigid , two-piece are more flexible. Some have sharp tips, others have rounded ones. It’s really down to personal preference which type electrologists go for.
