    I bought this for my son for his birthday and he loved it. He said he uses it almost daily. When I first opened it I thought there was a piece missing, but my husband found it right away tucked in on the right side of the box. Due to the shipping it must of got loose and hid itself, but we found it and all the pieces were there. My son said that he has already placed an order for the screens because he thinks that it makes a big difference. Very good gift.

    I just bought the pole and now im really regretting not getting the bowl too. I need to get it soon. I pulled out my old 18" straight tube that hasnt been used in like 14 years. Thank you invincipole.

    I have been using this product since a friend showed me hers. Really has been a lifesaver if you break your downstems all the time like me. I used a code and it actually wasn't that bad. Really a great product.

    Siren is so beautiful! This slide works wonderfully. My husband and I have been using Invincibowl for months and love them. Totally worth the money and having a cleaner bong ✌

    These work great. No restriction to airflow. Convenient and compact plus it fit a wide variety of pieces. When I reached out about my order, the customer service was impressively quick. Amazing solution for those of us out there who keep breaking glass!
