The small holes are cut to fit this jar.	Slightly smaller than the Beach-Nut jar, but still a perfect fit.
This jar fits the large hole.  Though tight, it is possible to make it tip out.	Slightly smaller than the one on the left, but still a good fit.

The two baby food jars are specific.  I haven't found any other suitable jars for the small holes.  For the large hole, the Mason jars work well.  There are many sizes and styles of these jars.  The two pictured are the ones I've been able to get.  I've also found that several brands of peanut butter come in plastic jars that fit quite well.  I found one that fit the hole so tightly that it would not tip out.  The advantage of the Mason jars is cost, about 65 cents each.  The peanut butter jars come with peanut butter.  My best advice is to take a paint tray to the store and try various jars.
