The Reindeer Antler Headband by HANSGO is lit up by LEDs and is a lot of fun for the kids. We have numerous headbands for the holidays, but this is a favorite of the kids. The on/off switch is kind of hiding between the two antlers at the headband, and you are able to switch between several light modes. As far as comfort, these are as comfortable as expected. I really like the age range this fits, from younger kids to adults, so everyone has a chance to wear these! If you are wanting to add a little extra sparkle for a party, parade or just around the house, this antler headband should be your next purchase! Very satisfied and we look forward to wearing these this holiday season.
