Balmain stock really really long hair on clip wefts which we ordered,coloured and used to make a really long fat multi braid for my hair for a photo shoot we did at our salon in May.
I cant remember how many strips come per pack but as its long you need quite a few packs to make it full/chunky enough if that makes sense and from what i remember it was really good on price.
If you do ring them,ask to speak to Ben specifically as hes very good and knows what hes talking about when it comes to hair as hes a hairdresser and extensionist himself.
Hes a fab guy!x
