This sleek Chongz Lemon Rind Percolator Bong 35cm. When it comes to bongs, bigger equals better! The ice pinch makes sure all your hits are nice and cool just by adding a couple of blocks to the stem. The extra length of the bong means that the smoke has further to travel. This in turn gives the smoke more time to cool which means every toke is smooth. The percolator again adds that extra distance for the smoke to travel but it also forces the smoke against the glass dome which removes some of the tar from the smoke. This means you get a cleaner smoking experience.
