Great product piece bought it because I thought that it might be actual hair clips and yes, it was 3-D printed material. I would say the boot should last a while. If you do keep them in good condition it’s a nice high-quality keep in mind. It is not oversized, but it does fit nicely. I would 100% recommend this product to people. I am surprised that it has not been sold out. Maybe it’s because people don’t know that it is what it is.
