It's new old stock – unused but may not be in original packaging, and there might be some shelf wear (as noted by the seller).

Made in the United States.

This tape is used for magnetic positioning systems – like AGVs (automated guided vehicles) or linear encoders.
The multicolor tape has magnetic properties that sensors read for navigation or position feedback.

California Prop 65 warning applies – standard for electronic components.

If you're maintaining or building a Roboteq-based system, this is the exact tape you need.
150 feet gives you plenty of length for loops or long runs.
