Mouth tapes to promote breathing through the nose

Brand new tapes in sizes S and M, which are applied when the child is at rest, even lying down, keeping the mouth open. Before use, I recommend consulting with an audiologist. Our child no longer needs them, as we have successfully resolved this issue. There are 3 packages: 1 piece size S and 2 pieces size M. Each package contains 90 tapes, and the packages are unopened. One package (€20) €14 or all three for (€50) €40.
