Swann Morton 11# Scalpel Blades Surgical Blade Carbon Steel Non-Sterile 100pcs

I do not understand how this has 5 stars. I purchased this for dermaplaning…but the blades do not fit in the handle. Each packet of blades has 5 blades inside wrapped in like tissue paper. It is hard to keep those other 4 you do not use right away sterile. If you are looking at this as an esthetician for dermaplaning do not buy. Blade does not fit handle
