Thc classic OG illadelph 9mm straight tube with a blue label and platinum outline. This tube was made in 2009. Attached to it is the illadelph upstem stemless ashcatcher that has a blue upstem and platinum label and inside of that is the illadelph stackable standard ashcatcher ac with a blue illadelph downstem in it. I take the hit out of an ice pinch slide with a glass carbon filter adaper with activated carbon rocks in it to keep the bong clean.
