The traditional ring binder; flexible and very easy to use. With matt black ring binder mechanisms, they are also that bit more exclusive as well. It is an ideal portfolio choice for those with ever changing contents who don't want the hassle of the screw post mechanism. They're also very easy to present when using a large volume of work. 
There is a choice of two ring binder folders; the fully case bound fabric over board option which we simply refer to as a Ring Binder and the Leather Ring Binder. 
The leather ring binder is available in either the 3.5mm thick leather or the 2.5mm textured leather in either black or brown. 

We have a number of different ring binder mechanisms with capacity ranging from 3 to 12cms.
The 2.5cm, 4cm, and 5cm mechanisms are avialable in matt black or silver. The other sizes are chrome only.

Whether it's a print portfolio box or a presentation portfolio box, you can design a clamshell box that is completely bespoke to you. This is a popular choice among graphic designers, as this allows them to present their ideas in style.
Your portfolio box can be made to fit any size of paper you wish and can be any depth required. Your box can be also be personalised.
There is a choice between a Full Clamshell Box which has two trays or a Half Clamshell Box which has one tray and a lid. The later has a magnetic closure and is actually ideal as a portfolio box. We can also fit a ring binder mechanism in either styles to produce a Ring Binder Box File.
