These were from coir lined baskets which don't work well for me because the plants dry out too quickly. But when I turn them upside down, they protect seedlings.
These stakes hold the baskets in place...
The stakes came from this which is pegboard accessories. I broke them off to use as stakes.
Those baskets also work when attached to pots and manage to keep the cats from trashing the catnip plants. Although the plants look pretty pitiful this year.
