Green Stuff World Weathering Sticks are disposable sponge paint brushes that can be used to create stipple effects on models, similar to using bits of a sponge dipped in paint. The weathering sticks are like a pencil and in a much easier to use form than bits of sponges. The sponge material is enclosed in a white plastic sleeve, and the sponge can be pulled out and cut off to provide a new surface. The sponge can also be cut to different shapes to create different effects.
The weathering sticks come in two sizes, 8mm and 15mm. The 15mm size comes two to a package and the 8mm comes 3 to a package.
