Leuchtturm: difference between OPTIMA and NUMIS

Hello all,

I'm looking for an album to put my coins and banknotes. I've found many references to OPTIMA and NUMIS albums on Leuchtturm website but I cannot find what are the main differences between the two types. Does anyone know?

Thank you very much!

Optima: Larger, more versatile, suitable for bigger collections or multiple types of collectibles.

Numis: Smaller, more compact, specifically designed for coin collectors with a focus on portability.

Thanks a lot! I've been looking a bit more at their website and I think what you have is the GRANDE: https://www.leuchtturm.com/ringbinder-grande-classic-design-incl-slipcase.html

With 6 double horizontal lines. The OPTIMA only has five: https://www.leuchtturm.com/ringbinder-optima-classic-design-signum-with-labeling-field-incl-slipcase-blue.html

There is also a slightly bigger NUMIS version: https://www.leuchtturm.com/ringbinder-numis-in-classic-design-with-slipcase.html 

Yeah you're right I wasn't sure and when I googled Optima it popped up as first entry but without size context both look similar. 😅
