I use Mavala. Excellent customer service and I love their natural nail care. They are getting better at 'being on trend' colour wise. They do have full size bottles but I have the mini ones and one is included with mani's & pedi's so they can take that bottle away which clients love.
Old fashioned, maybe? I see it as a well established brand with a loyal customer base. Certainly a bigger player in mainland Europe.
For me it works well, most of my business is L&P and Gelish/Shellac. So Mavala works well as I didn't want to carry a large bottles of polish that would go gloppy as they weren't being used much.
Hope this helps x
