Good quality binders with solid covers. Wish they came in D-ring versions though. For the larger binders those would be a lot better.

I have used 3-ring binders for years. I place my photos in protective sleeves and insert them into the binders. Unfortunately, most 3-ring binders don't hold the rings tight and secure, resulting in spilled pages all over the place. Then, I discovered CARSTENS. They are pricy but well worth the cost. The 3-rings hold fast and tight under the most difficult circumstances, like dropping the binder.These are made for medical uses; so, the tasks require the pages to be secure. I also love the colors. Each year, I change the color of the binders I am using; so, can tell at a glance which ones are from 2024 and the new mango ones for 2025.

I love the sturdiness of the binder and the color but several of them have a problem with the top ring. It won’t stay closed so my pages are constantly coming out. So disappointed considering how expensive these are.

Normally I buy at least 2 binders for my daughter because they break. This binder has held up perfectly so far!

I got this to put our working and daily recipes in. This binder is very sturdy and looks like it will clean up easily.It is constructed of hard plastic with a metal binding mechanism. The hinges are thinner plastic that may wear out over time, but I am not too concerned since it does not see an excessive amount of use.It is not the most attractive binder for recipes, but we were looking for something that would last and be easy to clean, which this seems to fit the bill just fine.
