I know I'd be too tempted to walk around all day going, "wakkawakkawakkawakka."
The Best Groomsmen Gift ever comes from Four Chamber Forge's Etsy shop:
Hand made top grain leather holster for a flask and a pack of cigarettes (or a cell phone). Snap closures keep everything secure. Holster is adjustable by the use of screw backed rivets, one size fits most. 6 oz stainless steel flask is included.
Yours for $145.
