My Fenris Games gas bottles turned up today and I am very pleased with them.
I painted one up in next to no time to see what it would look like:
The bottles are very easy to paint, and I will paint them in a few different colours, based on images I find on the net, although blue and yellow seem to be the most popular. White is too, but I don't want white ones.
Thanks to Fenris Games I have 18 gas bottles to use in my games.
