Pin-Up Large Perm Rod Pack 4s Perm Rods Large These are the largest rods available in the UK for perming & are used to both create volume, height & style support (without curl). When used on longer lengths the rods will achieve a 'beach wave texture' that can be washed & worn. If applied to shorter lengths (and permed) the result will be fullness & volume but without curl. From durable long term permanent curl results to flexible style & vintage looks or home colour application, Pin Up has become a brand synonymous with hair freedom.
