Would a pie basket do for your intended use? Admittedly I have not measured. I mention because we were gifted one way back when we got married, and it’s proven handy as a picnic basket as well as for carrying food/dessert to potlucks with friends. Plus we smile every time we think of the wonderful friend who gave it to us.
Our pie basket still looks like new after all these years, too. If only I could say the same about me.
