Very nice.
I used plastic freezer containers one year. They don't break easily and they stack neatly for storage. Cutting drainage holes in the bottom was easy. They also are designed to be washed and re-used many times over and can be sterilized with bleach. And the square base made them less likely to tip over than a container with a round bottom. I got totally fed up with foam and/or plastic cups that kept tipping over. The only problem with the freezer containers was that for some reason it was hard to get the plant's root ball to let go of the container. Next time I use them I might line them with plastic or something that I can pull on to get the plant out.
I bought some new canning jars last year. The cashier at the checkout counter couldn't believe someone was actually paying almost $1 apiece for EMPTY JARS!
