White & black vinyls are suitable for cars / outdoor use.
Holographic is suitable for outdoor use - it just won't last as long, more suited to water bottles, helmets, etc.
For indoor use for 5+ years & outdoor use up to 3 years.
Vinyl will last longer than stated if kept out of direct sunlight, e.g. car parked in shade.
Pictures are indicative of design only, you choose the size & colour.
Sizing: Length refers to the longest point of the design.
The transfer tape you receive may be clear or have grid lines.
Long designs may be folded for postage, it will only be across the backing paper & won't affect the decal itself

Permanent vinyl can be removed, but it may do damage to walls, paint, etc.
Isopropyl alcohol or goo removers can help.
