Hi Risol2001
I decided to 'allow' all my clients the option of purchasing a nail file pack. This includes: 240/240 Black Velvet(emery type), 240/1200 Koala and 180/100 Hard Shot (all from CND). After each use the files are sanitised with Chlorispray, wrapped in couch roll and placed in a marked envelope. I relay the price through to the client, £2.50 for the initial pack and £1.00 per replacement file thereafter.
I start by telling new clients about the possibilities of X contamination and to be quite honest, most of my clients are more than happy with this option. Anybody who doesn't will have a set of files that are used on anybody else who also doesn't want to (once again they are all sanitised). That is their choice.
Lets face it, I'm not making any money on these files, but at the same time I'm not having to lay out on them either.
All the best, Adele
