Caldera XL

Its a nice bowl elegant looking. The the hole in the bowl is a tad bit wide the herb falls through easily and the herb burns in a reverse funnel type way. It's nice a fun party bowl to share amoung friends.

EZ pack XL bowl

while most Pieces in the 14 mm range are very fiddly, the XL bowl makes things easy for my shaky hands.

It's pretty.

It's a good looking decent size bowl that's well made. Good impulse buy. Was hoping it would hold a metal screen but I managed to get the screen through the stem and it works great this way.
