Why are my presentation ring binders cracked and damaged?

Q.  We take presentation ring binders from you regularly but the last two batched have been cracked and are exposing the grey board underneath.  Have you changed supplier?  What’s the problem?  Can you replace them?

A.  We're sorry for the inconvenience and yes of course we will replace all that are faulty.  We have not changed supplier but I do we do know about this problem.  It is known as ‘pvc cold crack’; PVC becomes increasingly brittle as the temperature drops. When exposed to freezing and changing temperatures for prolonged periods of time, it can cause small cracks to appear in the PVC material.

This is not a common problem but occasionally we might receive a batch in from a manufacturer that has been in storage at too cold temperatures. We are inspecting our stock to make sure this doesn't happen again.
