☀️ Outdoor Durability:
- White and other solid colors (non-holo/non-shiny) have the strongest durability, lasting 5+ years.
- Holographic vinyl is prone to burning under prolonged harsh sun exposure combined with chemicals (ie car wash) (usually only affected around or after 6 months, this is different if the car is garage-kept, and can last 1-2 years).

Recommended replacement for outdoor shiny holos: 6-8 months

🏠 Indoor Durability:
Decals can last a very long time indoors (6+ years) if the decal doesn't get touched often, like a PC case. However, if it's on a water bottle, or laptop where you constantly touch or rub against, the edges could start lifting up.

Important note: do not wipe decals with a towel as the fibers from the towel can get stuck under the thin and intricate parts of the decal and cause it to start lifting at the corners. You can wash the decals as much as you want, just air dry or carefully spot dab it without causing any friction.
