No information on cartridge box regarding gauge

[Seigard]

I have recently acquired 2 boxes of cartridges as a gift however I want to be sure what gauge they are before I use them. One says 9-round liners, it's a cheyenne safety cartridge box, the other is from a local company saying 12-RLL (loose).
I've looked at everywhere on the boxes and on the cartridges but it mentions nothing of the gauge. Does this automatically mean they are standards?
Also what exactly is a loose round liner? I've googled but haven't been able to find much about it. Does that simply mean the needle hangs out further?

12 RLL = 12 is the gauge, meaning standard gauge, 0.35mm needle shaft.

If there is no gauge (08 0.25, 10 0.30, 12 0.35, 14 0.40 etc) listed, I would assume a 12 gauge.

A loose round liner is like a round liner but the solder finishes further away from the needle tips and so the tip of the needle group is not pulled as tightly into a point. A loose liner will give you a slightly thicker line than a standard liner of the same size…but not all that much.

I would avoid loose rounds IF I was working on something where I needed to vary my line weight in a single stroke, such as pulling out at the end of a stroke to get a gradual taper finish. This can be done pretty easily with standard liners (at least with smallish groupings) but less easy with a loose liner.

If in doubt give them a run out on fake skin.
