Schneider topball 850 refill in euro-format for ink roller pen 0.5 mm - what is euro-format?

I have no idea! All I know is the refills work very well - no problems at all. Just remember to remove (with a fingernail) the little blob of wax to stop the refill drying out.

is this the same as hauser bill 707 sf

Hauser has discontinued production of this refill! and are substituting it with the Schneider Topball 850 refill. so they must be compatible.

Will these fit a cross edge pen?

The only way is to try it against the existing Cross refill. It didn’t fit my Cross pen.

Are these threaded and do they fit Mount Blanc roller balls?

No these are not threaded, and I am not sure if they would fit A mount Blanc pen
