Did you get it right?
Two modern plastic closures do not fit this old garden-center counter.

The Answer
The correct answer is: the plastic slider seal on the soil sack and the white nylon locking fastener on the basil label.
Here is why
- The center Garden Soil sack closes with a molded white plastic slider running across its top.
- The BASIL plant label is cinched to its stake with a white nylon locking fastener.
Why people miss it
Both plastic pieces are small and neutral-colored, while the surrounding clay, burlap, wood, paper, twine, and galvanized metal look convincingly old.
