This is a standard drop down adapter that helps catch reclaim and keeps your bong or dab rig nice and clean. There are a lot of different sizes and joint options available for this drop down adapter so you are able to find just the right one for you.
I am happy with my pipe screens order.the product I received did not look like what was in the picture that I ordered from,there were only 2 styles/colors in what I received instead of the variety pictured,but they work well.
Very happy with my purchase. I am new to dabs and such. I love this little rig!! As described and very carefully pkg'd and it arrived quickly. I highly recommend this seller.
