Every year when schools open, wrapping my children's heavy textbooks with plastic rolls and tape used to take me hours and cause so much stress. But this self-adhesive film has made my life so simple! My kids and I now sit together and cover all their school notebooks in just a few minutes. Because it has box lines on the back, cutting is very easy, and it sticks perfectly without any folds or bubbles. The best part is that it is 100% waterproof even if the children spill water or juice from their bottles inside the school bag, the books stay completely dry and safe all year long. Every mother needs this.
