KZOBYD 4 Pack Rechargeable Bottle Lights Mini Cork Shaped Craft Lights USB Powered Fairy Cork Lights for Wine Bottles Party Décor Christmas Halloween Wedding (White)

They do fit in a wine bottle but not snuggly. I expected a more secure fit, but they will work. They are also useful for other things as well. Left them on overnight and they still had weak output the following morning. To turn on/off hold the main body and turn the light. There are no instructions on how to turn on/off.

Love the look when used in reverse decoupage bottles. But was very disappointed when one of the lights literally fell apart when trying to show someone how to charge the battery. I will buy again, however I will test them all upon delivery.

These were not quite what I expected, they don’t fit into the bottle opening the way I wanted. But they are still very useful and provide a little sparkle to old wine bottles placed around the house to lighten up dark corners.

Pretty.Battery life is only 2-3 hours.Production quality: one of the usb covers comes apart when you want to plug it in to recharge.

I had two broken ones. They are hard to pull apart when you need to charge them.

Love these lights, best part is they are rechargeable. No batteries, which I have gone through a lot on other similar products. Well worth the price !!!!

I like the fact that these are usb chargable... no batteries. But, They were not as bright as I had hoped, and will probably work best in clear bottles.

These lights are not very bright so they don’t illuminate bottles very well. I liked the concept of having a single light which can shine down inside the bottles. I haven’t tried putting objects in the bottles such as marbles or colored water but the lights might work better in that context. I can’t really speak to the battery life since I’ve only had them for a little while.
