Overall this is a decent binder that does the job. The outer is great quality and zipper should last a long time, but I feel this is where all the cost for design and production went.
The colour was not what I expected — I ordered the blue and it was much lighter and had no where near as much black contrast as the example. The inner sleeves and pages I suspect will fail over time, and maybe sooner than I’d like, which for the price, I expected better. My binder is not 100% full and the pages are already visibly stressing from the weight. The side loading style is a modern favourite, but this particular design means the turning of pages causes some of the cards to slip and almost come out. I am always having to push the cards back into place. Maybe a simple button clasp to partially close each sleeve would help prevent anything from falling out unexpectedly, but granted this could cause en eye-sore. Shipping to the UK is pretty expensive (£17), so unless improvements are made, I can see myself going for a cheaper option which will do the same job and not cost a small fortune.
P.s. I bought the rigid sleeves and penny sleeves with tabs — no flaws here, they are exceptional.
