My friend is selling a manifest glasswork bong for $115 Specs Straight Tube 3 Ice Pinches Five Inches Long 14/18 mm Low Profile Diffused Downstem with Black MGW Label Included 14 mm Funnel Slide Included 7 mm Heavy Wall Glass 15.0" inches Tall he says he will even clean it before I buy it stem and all. it has no chips/cracks or anything like that.
Manifest Glassworks - 7 mm Straight - Blue Label Sounds like this is the tube your looking at, looks good to me. To answer your question though yes Manifest to me would be considered a legit company. Sounds like a good buy for 115 but you can get a new one for 140 also.
i payed 125 for this tube new. its a decent pipe the quality control is not so good though. watch out for the base mine was super thin. i dropped this tube from 2 inches of the ground onto carpet and the base shattered. also i was not happy with the quality of the joint weld it is pretty sloppy. so 115 is not bad at all if you like it go for it.
a company who has nothing but a perfect reputation. a company that stands behind their product. a company that produces glassware that customers desire
