We do have tips that really help maintain the tights so they last longer.
Tip #1 Always wash tights inside out, it keeps the tights from getting catches.
Tip #2 Hang tights to line dry, the dryer might ruin them.
Tip #3 Make sure your child's toe nails are cut, so the sharp edges don't tear the tights. (one of the main reasons why children have holes by the toes)
