Thin Pockets for small birds like conures, caiques, Indian ringnecks and more.  Don't forget, this one is meant for destruction with the leather thickness at 3-4 oz.  This pocket size dimension is like any of our Small Pocket sizes at 4 inches wide by 6 inches tall.  The hole size in this Pocket size is geared for conure sized Zupreem food or perhaps smaller Roudybush food to fill in it.
