"Cleaning the Se$$ions piece with the cleaning caps reminds me of shaking a martini. Fucking beautiful."

Where have cleaning caps like this been my whole life?! Wow, if the session bong wasn't great enough, adding these caps really puts the icing on the cake...

I've cleaned a million pipes, bongs etc. and these little caps just changed the game. Usually, you get stuff all over your hands and now mess-free. Game Changer!!
