    Crystal Flex Unibind Covers

    Posted by Stephen Snow on Apr 25, 2024

    These are very excellent covers for the types of real estate presentation binders I make. My only wish is that you had a sampler package where we could purchase several different sizes in one package. Shipping and customer service was excellent and I will be a repeat customer!
