Stanton, 89 is the length.
It’s to the right of the “12 gauge” descriptor on the box.
The other pic shows 70mm , which , when divided by 25.4 mm/inch, is a standard 2.75” cartridge.
The box artwork is excellent, IMO. I like how the drone gets more advanced with the stouter load.

3 ounces of lead is market-hunter territory out of a small punt gun.
Not that there’s anything wrong with that…
