These pouches are perfect for classroom treats or handing out candy for Halloween! Each pouch is approximately 5-1/2" x 4-1/2" when assembled and holds treats up to 1/2" in width, such as chocolate or gum (as pictured). The pouch is one piece and is compatible with both the 8x12 and 12x12 mats. Simply fold in half, placing small bits of adhesive on the curves of the pouch, then fold the circle flap down. Adhere detail cuts in place. Fill as desired! You can see more here: http://jamielanedesigns.blogspot.com/2016/09/artisan-pouches.html
