A smart combination of a bottle cap and a few hoses on top of your plastic bottle is all you need. Small, discrete and handy. A rather stylish smoking accessory you don't have to hide.
Byba fits on any type of plastic bottle with a universal thread diameter of 28 mm. You don't have to cut anything and you don't need to punch any holes. It's quite practical, since it only measures 5.4 cm in height. Small enough to fit in the palm of your hand, fits in practically every jacket or trouser pocket as well.
It's made of aircraft grade Aluminum which can withstand up to 660 °C without producing any toxins or changing form, so Byba is quite indestructible and very safe to use (the hoses are 100% medical grade and FDA approved).
What is the asking price of this little wonder? 25 €.
