One cent seed growers.

How delightful to stab through a stack of these ugly white plastic cups. Unlike the slightly more expensive (and less offensive to the eye) clear “unbreakable” cups, these white cups put up no fight whatsoever, and the knife slides through up to 10 without a problem. Quick, easy, and best of all - cheap! I flew through them - making new homes for the okra and some peas.
