    "I've gone through cheap flasks before and this one's different. The compartment up front is actually useful, not just a gimmick. Fits in my jacket pocket easy and doesn't rattle around. Gave one to my dad for his birthday and he won't stop talking about it."

    "Bought this for a buddy's bachelor party and ended up ordering one for myself too. Solid weight, doesn't feel cheap like the stainless ones you find at the gas station. The funnel actually works without spilling everywhere. This is becoming my everyday carry now."

    "Honestly wasn't expecting much but this thing is built well. Latch is tight, no leaks after weeks of use, and the case up front holds more than I thought it would. Packaging alone made it feel like a real gift, not some cheap Amazon knockoff."

    How much does the flask hold?

    The Vault Flask holds a full 6oz, enough for a generous pour whenever you need it.

    question_mark

    Will the compartment leak into my drink, or vice versa?

    No. The storage compartment and the flask are completely separated and sealed individually, so nothing crosses over.

    question_mark

    Does it come with anything else in the box?

    Yes, every order includes a precision stainless steel funnel for clean, mess-free refills, 2 shot glasses and 1 gift box.

    "Fits Right In My Jacket Pocket"

    Slim enough that it doesn't print or weigh down my jacket but holds plenty. Easy to forget it's even there until I need it. Exactly what I was looking for.

    "One Piece, No Extra Junk"

    This is exactly what I wanted. Sip and storage in one piece, nothing extra to carry around. Looks great sitting out on the bar at home too.

    "Doesn't Feel Hollow Like Others"

    Solid weight in the hand, you can tell it's actually well made. The compartment door snaps shut tight and the whole thing feels built to last.

    "This Thing Is Built Different"

    I've owned three other flasks and none of them held up like this one. The compartment up front is actually useful, not a gimmick. This is my everyday carry now.
