Series made by pirate UAE label Thomsun Original
The cat# scheme is generally ENB-### / ENB - ### / FNB - ###
The most initial releases of this series were branded as The Ultimate Collection (12). This appears to have been changed somewhere between ENB-8 and ENB-13.
The label design appears to have been stolen from The Collection (6), a UK budget label.
