We bought these some years ago. At the time, for some reason, covers were impossible to find in stores, either at Williams-Sonoma directly (where we got the mixer itself) or even at places like Linens N Things.Great for storing cookie dough in the fridge. You can even fit the attachments inside the bowl and cover it all when not in use.(We have the Ultra Power with 4-1/2 Quart bowls.)
