I love making panda sandwiches with this! Not only is it fun for me, but kids enjoy making sandwiches with these adorable panda faces too. I recommend not refrigerating the bread before making the sandwiches because the face doesn't work as well, and the seal isn't as tight, but if you keep your bread on the counter or in the pantry, you'll have adorable faces in no time! Also, don't be too greedy with your filling, or the sandwich seal won't hold. XD
