To make certain nothing will fall out or detach when you're flipping and swapping pages, the rings that hold the pages within Rocketbook Pro Page Packs together are clamped and sealed shut.
We do not recommend altering Page Packs, or manipulating the steel rings they are bound with. It might be doable with some considerable effort, but we just don't think the re-closure will be as clean as when our machine originally clamps the rings. Custom Page Packs are for sure something in consideration for the future, though!
Note: It is not recommended to use letter size Original Pro Page Packs with the letter size New Pro Cover. Letter size Original Pro Page Packs are best if used with the letter size Original Rocketbook Pro that contains built-in pen holder. Learn more here.
