The one drawback to these clips: almost impossible to sanitize. If you put them in the sanitizing chemicals then they are likely to rust, but you HAVE to sanitize reusable implements in a salon. Even the owner of the salon I'm at told me, 'I have two sets. One of them are simply for greasy jobs, and the other for jobs that I can rinse them afterwards.' So she reuses the clips for 'greasy' jobs without sanitizing because it's that big of an issue. If they had a very thin rubber coating or something, then that would solve the issue. But, becAuse of that, I see these almost as disposable. The price is cheap, but not cheap enough for me to buy box after box and dispose In between.
