Butan-Kartuschen?

Norway is a big place, where are you going to be?

If it’s a [standard cartridge/standard connector](https://en.wikipedia.org/wiki/EN_417), you’ll find compatible canisters at stores like Biltema, Jula, Clas Ohlson, Thansen and XXL.

I know some Campingaz products use proprietary connectors though, but I don’t know if that applies to the one in your picture. As far as I know the only physical stores in Norway that carry the brand are Thansen: [https://www.thansen.no/camping/grill/gass/gassbeholder-campingaz-cp250/n14742/pn968751](https://www.thansen.no/camping/grill/gass/gassbeholder-campingaz-cp250/n14742/pn968751) But they have shops in a lot of locations so it shouldn’t be a problem to find one: [https://www.thansen.no/butikker](https://www.thansen.no/butikker)

If it is a standard connector though, I’d suggest going to either Jula or Biltema – they are usually the cheapest for this kind of stuff.
