NO WAY!!! First Ever Japanese 151 Booster Box With NO MASTER BALL?

You won't want to miss my reaction in this video. I opened a booster box of Japanese 151 and there was no Master Ball card inside. You are guaranteed one (1) Master Ball in each box, and out of the 15 I've either opened myself or witnessed a friend open this is the only box to not have one.
I do not own the rights to the song used in this video. Song used:
We Go Up (Instrumental) - Nicki Minaj, Fivio Foreign

Hi. Did you get this box from a reliable source? It might be tampered with unfortunately.

I bought it from one of the local card stores I frequently shop at, which is the weirdest part…I also wondered if it’d been tampered with though
