The Polyurethane Film (PU) protects the tattooed skin whilst still allowing it to breath and heal naturally. For application instructions, see packaging. Available in 10 metre rolls or in packs of pre-cut strips. The EZ Defender Premium Roll is an extra thin and extra gentle on the skin version of the regular.
