Invisibobble HairHalo Sparks Flying Limited Collection - We're Ornament To Be.The Invisibobble® HairHalo has two special features: the individual shape and its material. In places where it's too tight or too loose, it can be individually adapted to the shape of the head and worn all day – without pain and uncomfortable pressure! As a result, the HairHalo offers a comfortable and gentle alternative to conventional hair bands and, as usual from Invisibobble®, it's traceless!
