Hi Alessandro,
Thank you so much for your order and for taking the time to leave a review! I noticed that you mentioned the binder can be a bit tricky to open and insert the toploaders when both sides of the page are filled. I’d love to share a couple of tips that could make it easier for you to use.
When inserting toploaders, it's best to slide them in with one corner first. Once the toploader is partially in the pocket, push it straight into the back of the pocket. When taking them out, there's a little trick you’ll get better at over time. Instead of opening the pocket with one hand and pulling the toploader out with the other, use one finger underneath the toploader to slide it out easily. It really becomes second nature the more you use the binder.
