Masterbind USA's  knowledge and experience with book binding was very helpful for me and my company. We use their hardcover books in linen for our company reports and client portfolios. Masterbind was able to create a customizable cover for us that was professional and unique to our brand. I highly recommend using their services!

GG MitrescuProduct Manager

I recently purchased the Masterbind trimmer stand alone unit for my printing company. We attached it to our roll laminator from Royal Sovereign and use it for our medium to larger runs. The adjustable slitting blades and time sensors are well worth the purchase.
