The Peco Pecoscene Pro Grass Micro Applicator applies static grass to areas of your layout or diorama where you've applied a layer of scenic glue. The applicator electrostatically charges the grass so it stands up on end as it's being applied creating the effect of real grass. Perfect for fields, meadows, lawns and embankments. This applicator is suitable for all static grass lengths up to 1/2" 12mm. The Pecoscene Pro Grass Micro Applicator works off a standard 9V alkaline battery (not supplied), which will last, on average, for 60 hours of use.
