It has some shine, so it is not recommended for lace units. The lining is red but the tape is clear. HoldExtended Wear (1-2 weeks) tapes are perfect for people who need something more than just for everyday use, but also aren't looking for the longest bond. This is a popular type of tape because many people reapply their units in less than 2 weeks.
