i am very guilty of purchasing products from ebay!!!!!! And yes they have been creative and they came from a lady who was closing down her creative salon, but it was a strictly for proffessional purchase only!!!!
I look on ebay alot i am a big fan , but tend to stick to the proffessional products and to sellers who insist that it is a qualified nail tech that prchases the items.
There are so many sellers on there selling all different kinds of 'home' xtension kits be it profesional or highstreet brands but i have to say it is very rare that you see creative professiona products for sale on there . although i have seen solar oil on there many times!!!!!
As for the sellers who willingly sell professional products to the general public well u can tell them a mile off!!!! avoid like the plague!!!
