I finally found it. The perfect binder. Well, near perfect anyhow.Pros:-very well made with nice materials-quality zipper. Best you can get actually-beautiful and durable SIDE LOADING pages-when it’s closed, it feels more like a book than a card binder, and they close flat, meaning they don’t ramp like a 3-ring binder, so you can stack them easily-plenty of pages to store and showcase many cardsCons:-doesn’t completely “seal up” in the way i was hoping. Definitely a better solution than a 3-ring binder, but fluids and dirt can still find a way in. Not a deal breaker though and I’m unsure if a binder like that even exists-possibly overpriced-as with any fixed page binder, organizing cards and sets can be quite the task to rearrange. Small price to pay though for such a protective solution.Conclusion:Simply the best binder I’ve ever owned, and I’ve owned quite a lot. These are especially nice if you’re coming from 3-ring binders, as you’ll enjoy the benefits of side loading pages with cloth backing and a zipper seal. Don’t store your cards in anything less. You won’t be disappointed in this one and I’ll be back for more for sure.
