Iridescent and Silver Flip sequins with Iridescent scallop lycra lining. This is my first batch. I find the white lights and these light sequins cast the light be best. Color lights or sequins just are not bright enough.
The batterys last a long time and are durable; but they are electronic and subject to shorting out if they are used harshly.
The batteries are replaceable. Disclaimer: The Fairy lights can be quite sensitive at times. If they are smashed they can short out. The lights are a novelty I am looking to improve them.
