@thisISjoel be very careful when buy a Synthetic Fibre because their are still 3.5 Generation means v1.0 on the shelf's without even knowing a 4th Generation Synthetic Fibre v2.0, my advise would be is email them to double check otherwise you could end up buying v1.0 Synthetic Fibre without even knowing so just be careful. I don't own a Vie-Long brushes so I can't really give you enough information at this stage.
