This Artisan dough tray lid fits the Artisan dough tray.
Keep in mind that you do not need one lid for every tray. The DoughMate trays stack on top of each other and interlock so that the stacked trays seal the ones below them. You only need a lid for the very top tray.
Depending on how you plan to stack them, and what kind of room you have in your fridge, you may find that one lid per two trays works out well.
