07 — Common questions
FAQ.
What's the difference between the materials?
Standard adhesive sticks to the front of a surface (walls, doors). Front adhesive sticks to the back — apply it on the inside of a window and it reads correctly from outside. Great for glass storefronts and vehicles.
Which size should I choose?
3 × 3 in for close-up spots like door frames and vehicle windows; 5 × 5 in where it needs to read from a few steps back.
Will it hold up outdoors?
Yes. The UV protective coating makes it waterproof, weatherproof, and scratch and fade resistant.
How many come in a pack?
Six per pack — enough for multiple doors, windows or vehicles.
