works with A6, but doesn't feel like it's made to be used with it, if that makes sense? Stays on as long as tightened, but the shape is also slightly different from the others. all in all I'm satisfied though because these save me a ton of money vs manufacturer options. all individually packaged and labeled. these also seem to be better than the 12pin pack I've gotten in the past.

Excellent and as expected. Individually sealed cartridges are just as expected. Fantastic deal too! I've very satisfied with this seller and my order.

I don't use them yet, I'll let you know, but it looks good quality and package arrived sealed
