Unused Hello Kitty Viper Mini shells in Pre-Builts are sourced as factory-new from a third-party supplier; official retail provenance is not verified. Minor paint imperfections or light handling and transport marks may be present.
Installing the Mod Kit requires trimming specific plastic sections of the Viper Mini shell. This is a permanent shell modification, so installation is not drop-in. No soldering is required.
