model to test russian hair ?

fully qualified and insured extensionist wanting to try a fab new russian range extensions. normally prices at 260 for russian hair i am offering at a discount price of 170 to cover costs with free fitting. All the model will need to do is keep me informed on how the hair as after wash, styling and what condition the hair is every month the extension technique is micro-rings so no glue involved and after 2-3 months depending on your own hair growth and whether the hair is still in good condition the same hair can be retightened for 60
