Is this the ink cart known as international size?

There are two standards. This is the smallest and probably most common. It will fit some pens which also use the larger

Does anyone know if these will fit a Manuscript fountain pen? I like the Manuscript i have it is the leasst expensive one on the market.

I do not know, but it is smaller than the normal fountain pen ink. For what it is worth, this pen writes very well.
