From the release:
Sally 4th has added a range of Burst Templates to our Pulp Alley accessory collection.
This includes 3" Burst, Heavy Burst, Short Burst and Long Burst.
Each template is available in either 3mm Clear Perspex, 3mm Volcanic Orange Perspex and 3mm Medite (MDF).
The templates are all hollow so that you can place them over the top off miniatures and terrain.
