  Steel Crystal or Unicover Flex?? You still have a choice 

Unibind has now ceased production of Steel Crystal and Steel Matt covers and are suplying Unicover Flex as an alternative. Unfortunately they have changed  the sizes also. The new sizes have created an enormous gap for small document users. The 3mm (10-25 pages) is missing (our biggest seller). You now have to choose between Unicover Flex 15 (pages) and Unicover Flex 40 (pages). So if you want to bind 16 pages you will need to use the Unicover Flex 40 which will leave an unsightly gap big enough to fit 24 pages.....thats a 3mm gap in a 5mm spine!! Also the new spine is a lot deeper to facilitate crimping but results in more lost page margin. Your alternative is to use Compatible Steel Crystal.  

We have been selling Compatible Steel Crystal and Steel Matt since May 2015 and have not had one single complaint!

The Compatible covers work just like the Genuine covers. Most people cant even tell the difference.

The bottom line is that by using compatible covers you save money without sacrificing quality. 

Payment methods  Paypal, Credit Card or on invoice. Your first order automatically opens an account.
