This Spirit string of miniature lights every several inches is 7 feet long. Very bright. The power pack is 1 1/2 inches tall by 1/2 inch wide. In the Demos you see we used the battery pack to actually support the mannequins bun in back which hides the pack.
The pack is plastic. The on off switch is on the pack it slides left to right. The battery are small round and replaceable but we left them on and they lasted 72 hours straight so short on and off sessions for a few hours at a time are perfect.
You can cut the light string shorter if you want and the lights on the battery side will still work.
We send attachment suggestion items with it. Velcro and wig pins.
