Paint in spray. The Montana Black Spider 150 ml is the original spider web effect can. This easy to hold 150 ml can creates impressive black spider web-like effects through its high-pressure output. The closer it's applied to the substrate, the tighter the web lines. The further away, the more organic the effect becomes. Often used for calligraphy techniques, the line output can also become sketchy and pencil-like when the original FLAT JET WIDE CAP is replaced by a SKINNY CAP or NEEDLE CAP as you can find in the Montana Cap range.
