VAZ car key

 (Sixpack) is an item in Escape from Tarkov.

Description
Key from one of the VAZ cars (commonly referred to as a Sixpack)

Trivia
VAZ is Russian for Lada car.

Sixpack is probably a bad translation of SHESTERKA, meaning LADA-2106 or VAZ model 6 (thus six-rka). Word created similar to tushonka (stewed-nka) or ushanka (ears-nka meaning a hat with ears).
