For the holidays, Michaels is selling candy coated sunflower seeds in a clear container shaped like a Christmas tree bulb. It is rather thick, but the inner diameter of the base is slightly smaller than an 18mm motor casing.

Something else to look at are the clear plastic capsules in the vending machines at the front doors of some stores.

If you can wait until springtime, some Easter eggs are close to BT-60 in size.
