glass-on-glass diffused downstem

Very well made...I love those diffused slits near the bottom (3 on each side near the bottom of the down-stem) which helps with the percolation of the water to circulate the smoke coming up and makes for a full smooth toke! SPOT ON!

Too long.

I bought it after hearing the stem size, but it is a little too long and hits the bottom and doesn't suck well.
