Reviews
Fixed the plastic sign with cable ties near an access point. Solid build quality and still sticks out well from a distance—even on overcast days. Feels properly professional.
Went for the Correx board on a temporary barrier. Light enough to shift as needed, and the print hasn’t blurred or bent. Does exactly what’s expected.
Used the self-adhesive vinyl on site hoarding. Holding tight even with dust and grit around. Clear and bold—cuts through the background clutter nicely.
The rigid plastic version sits well on a fencing post by the gate. Colours still pop despite a few heavy showers. Looks serious enough to keep the public back.
