it's a bit tough to count/see them but does anyone else count less than 20 arms on that tree? SNOB Glass - Custom Black and White Stemless 20-arm Perc Glass Bong with Ashcatcher - Bongs and Waterpipes - Smoking Pipes - Grasscity.com
It says it is a double ring tree perc so there is probably 14 on the outside and 6 on the inside or rather some other combination adding up to 20.
I dont really see that "ring of trees" when I look at the perc though, it just looks like a normal 10-14arm tree perc...
