To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
I bought these for my university project. My lecturer, a professional printer and binder, commented that these were really great quality for the value and so far I've had no quarrels with it. My only "problem" is it would be better in a nicer box for storage use, but other than that I really like them. The waxed thread is a bit on the low-quality side, however, the bone folder is really great. Would recommend to newbies at binding!
