Showing the 9" x 4" Collection Bowl, and the 5 3/4" x 4" Mash Squeezing Bowl w holes. Both stainless steel. The latter bowl holds the muslin sack filled with alcohol sodden herb. Holes in the Squeezing Bowl are 5/32 or 3/16 towards the top and 1/8" near the bottom. The "Mash" is compressed into an adobe-like hunk, so don't worry about re-absorbtion of the pressed tincture.
