Too small
I didn't get my measuring tool out and when I got them they're too small way too small

Very stealthy
I originally bought some that were longer than these, but they were difficult to clean. These are easy to hide and eezy-peezy to clean. Tickled with this purchase.

Sturdy Glass
These tubes are sturdy. They work great for smoking, about 3 hits per bowl. Glass does not get too hot to hold. Brush works great for cleaning after soaking tube in isopropyl alcohol for 24 hrs.
