excellent. GRAV is always great.
Used grav ash catch now maybe a dozen times now ... keeps my 16 in grav straight pipe clean ... thick glass well made ... more time enjoying and less time cleaning
I love this ash catcher mainly because of the removable down stem. Makes cleaning so much easier and the function is phenomenal! 420 science is my go to shop for all things smoke related. Quick shipping my items always arrive a day before they say they should, which is a plus.
Works great, awesome glass!
