Did you get it right?
One modern package appears among older hardware-store supplies.

The Answer
The correct answer is: the clear plastic blister-pack screw kit.
Here is why
- The loose bins, paper envelopes, scale, oil can, and ledger fit the old store.
- The clear molded blister pack is the modern item that does not belong.
Why people miss it
It contains hardware, so the category feels right, but the plastic package style gives it away.
