Alpaca Bowl Company is known for its high quality, hand crafted and unique color combo bowls.  The Predatory by Alpaca is one of their first creations and features a foil bridge.  The foil bridge across the top of the funnel opening is there to prevent the from being dragged down upon inhale creating a clog and tight draw.  Each bowl is hand made, which means no two are alike and color finishes as well as size may vary slightly but that is what will make yours unique to you.
