I will sell the entire set up which includes the microneedling machine, plus all products you need to get you started- I have about 15 treatments worth of products- each session of needling you should charge at least $250.

If you set up account with these guys they are super helpful- training sessions are offered in Tauranga every few months and cost you $45 so you can be confident providing this service to your clients.
