I make these antenna with twisted teal green wire and discreetly bind them onto a black metal alice band. There is a lot of fun to be had with these antenna! They are perfect for women and girls alike and the ideal accessory for halloween, costume parties, festivals, cosplay, photo booths, burlesque outfits, kawaii fashion and dressing up. For even more fun use this tiara to accessorize hen nights or bachelorette parties. The durable alice bands I use are flexible and stretch as needed to comfortably fit everyone from children over five years old to adults too.
