The cartridges fit in, but they have a rectangular shape and lack the widening that prevents the cartridges from slipping in the station. The side groove/ridge guide is almost identical. If you don't move the station all the time, it works fine for me.

According to Galaxus, yes, but I'm not convinced. The edges on the old cartridges held better in the case. If the case is stable and you don't move it, it works.
