I got the thic boy

So this is actually my second time ordering a replacement downstem because we be clumsy at my house. This last one got RKO’d by the dog and cat playing around and broke off clean but still inside the bong (broke the bowl stem clean off too). And due to the fitment being nearly perfect it was a struggle to remove the remaining half of the downstem still inside the pipe. I eventually found a campfire tool for cooking (long bar with two prongs and was able to wiggle the stub of the stem enough to break the vapor lock and slide the other half out. Last time I went with the half size down as that’s what customer support recommended. This time I got that one and the longest one, and the longer one (5.5”?) actually fits better, but they both work. I will say you can tell it’s handmade. This 5” is longer than the last one and fitment is not as close as previous one. If anything the last replacement fit too good, we dealt with that vapor lock issue at the joint a lot.

Hi Colton,

Wow, what a story! Sounds like your downstem has been through quite the adventure, RKO’d by your pets and all! We're glad you were able to get the broken piece out (campfire tool for the win!) and that you found the right fit this time.

Since each piece is handmade, there can be slight variations, but we really appreciate your detailed feedback, it helps us keep improving! If you ever need another replacement (hopefully not too soon!), you know where to find us. Thanks for your support and the awesome review!

Question

Hi I have the squared up 9mm thick beaker bong and was wondering what size is the stem for it . I purchased the 5 inch stem and it seems to be too big for it, it doesn’t pull well. Would it be the 4 1/2?

Hi David, thanks for reaching out. The 5 inch stem is the recommended downstem size for the 'Squared Up' but since our pieces are handmade some measurements may vary so there are times that a 5' will not work perfectly to the 'Squared Up'. We'll send you a 4.5' and you might need to adjust the water level for it to work perfectly with your piece. We'll send you the details of the replacement downstem via email. Warm regards,
