Captain Stag Regular Gas Cartridge 2 full and 1 used

Compact size for easy portability. Estimated usage time is approximately 2 hours (when used with a gas burner). Also recommended for disaster preparedness. Its compact design means it won't take up much space in your emergency bag.

Purpose: This is a dedicated cylinder (OD can) for Captain Stag gas burners and lanterns.

Two are unused, and one has been used about 1/3 of the way.
I have weighed them. Please check the images.

Thank you for looking.
