gamegenic just sleeves v prime/matte mini european

Hi all,
Struggling to get my beloved gamegenic matte in mini european, so looking for a replacement.
Have found the just sleeves version for a good price but not sure if they are the exact size. Does anyone know?

I know with the standard sized just sleeves, they are slightly longer. Don't want to buy too many packs of these and not have them fit in my inserts!

Thanks
