Having mechanical tapes are both sides is one of the specifications of Easy Life tape diapers. These tapes are free from chemicals, hands are not stuck onto them by touching, and they seem to be a little rough. These tapes are locked into the diaper outer layer lint when attached and may be detached and attached frequently. For correct and better attaching the tapes, press them mildly with hands when attaching and attach the upper tapes tilted and downwardly. Refer to Easy Life Tape Diaper page for further details.
