Bought this for my brother's 40th and he genuinely thought I'd gotten him a book about fly fishing. The 4oz flask inside is solid stainless and fits perfectly in a jacket pocket, no leaking so far. Sneaky little gift that got way more laughs than a normal bottle would have.

The look on my friend's face when he opened what he thought was a boring book and found a flask inside was priceless. The 4oz stainless steel one is the perfect size to tuck in a coat pocket, and it doesn't leak a drop.

Gave this to my brother for his birthday and he cracked up when he opened the "book" and found the flask inside. The 4oz size is perfect for a couple swigs at a tailgate, and the stainless steel doesn't leave any weird taste.
