This 30-pack of round Viviana Dots is designed to help you discreetly mount a lavalier microphone to your subject while also reducing fabric noise. Each sticker features a thin foam layer sandwiched between super-sticky hypoallergenic adhesive tape. The hypoallergenic tape is safe for use on skin and clothing and won't leave a mark, while the foam layer insulates the mic from clothing and fabric for less rustling and contact noises. This round shape is well suited for use with DPA lavalier concealers.
