Ready to go to space with this Astronaut silicone pipe!?
 
Silicone body and tempered glass bowl.  The "moon" has a front cover, which is great for on the go.  Easy to clean: just remove the glass bowl. It fits snugly right back into the opening and won't ever fall out on it's own.  Back of "moon" is removable for storage or cleaning.  A very unique piece!  
 
Measures 4.75" long.
