I've used it about 3 times, so there's about 8 minutes of fuel left. Please refrain from purchasing if you are looking for a new item. CAPTAIN STAG CS-500 LPG cartridge 230g, perfect for barbecues and camping. - Brand: CAPTAIN STAG - Model: CS-500 - Type: LPG cartridge - Application: For barbecues and camping - Contents: 230g Thank you for viewing. ※ (Photo 4) The number written on the bottom of the gas cartridge is the manufacturing date (20200220), so the expiration date is 7 years from that date. There are 2 years left until the legal expiration date, so I'm pricing it low.
