During the Battle of the Denmark Strait anniversary game I realised I really wanted better looking splash / blast markers for naval wargaming. Nic suggested Irregular Miniatures' 'Two explosions and two shell craters' (code GWV14) which are also available from Eureka Miniatures (code IRR-GWV14).
Designed for 6mm WWI wargaming, these are perfect for naval games and were very easy to paint up (black undercoat, heavy grey dry brush, light white dry brush, white highlights).
I have another 10 (in both sizes) that I'll paint up black to use for land warfare. Really happy how easy these were to create. With the current lock down due to Covid restrictions, I have no idea when I'll get to use them.
