I designed this because my old floss containers lid would pop off way to easily. I made the lid have a snugger fit and I was able to reuse the little cutting tool to cut the floss, also it was really hard to thread the floss through the tiny hole in the lid so in my new design I made the hole bigger and made it way easier! The last litte design I add was in the holder it self I add a peg to hold the floss up instead of the floss floping around/getting tangled up inside! Now every thing works perfectly! Hope it can help you!

side note I had to use a clap or vise to press in the blade!
