I have the feeling that nail polish remover pads are a bit of a phenomenon right now always acetone-free. Since I was young girl, my mother maid me use the ones from Mavala. If you are not familiar with this well you should. This swiss brand of nail care and beauty has been around for more then 50 years and therefore really knows its business.
Lately pads came back and you can find them anywhere but does it mean that the quality is always the same?
The ones from H&M are nice and easy to use without to much struggling.
The ones from Héma are thick and the product doesn't seem to really cling to their surface.
Lastly the ones from New Look are really efficient without smelling too much but as they are quite thin, they tend to spread the product rather than taking it off.
