Does NS International charge a €7.50 fee when buying an Interrail paper pass at the station?

Hello :)

I plan to travel this summer with the Interrail Pass, and I'd like to buy the paper pass.

I was wondering, if I purchase the paper pass at one of the NS International desks at Dutch train stations, will there be a 7,50 euro per person supplement on top of the pass price? Or does this supplement only apply to point-to-point international tickets?

Thank you!
