opinions... would these for for homemade split cakes?

I was looking through what I have on hand and I remembered I have a bunch of small flat square containers filled with beads.  They are pretty small.  Only 1.25 inches square and about .5 inches tall.  Think they would work for small split cakes like one strokes?

Yes, that's about the size they used to be. They are harder to load than the new longer ones but they will work. The actual one-stroke containers from TAG are 1.125" X 2" (interior measurement).
