Summary:

It is all smoke and mirrors! As you engrave, debris such as smoke and dust land on your focal lens, building up a layer of residue over time that absorbs laser beam power and can stain the lens permanently. Eventually, this lost power will affect your machine’s precision and throw off your laser settings. To keep your device running at its full potential, we recommend inspecting and cleaning the optics system once a week and replacing the mirrors or focal lens as soon they get damaged.

1 x CVD ZnSe Focus Lens

Great for busy feet

My five-year-old daughter loves these Skechers slip-ins—and she is not easy on her shoes! You can see in the photo, she’s already put plenty of miles on them. They’ve been through the washing machine at least twice and still look great—the bright colors are a big hit with her and they hold up well in the wash. One of the elastic bands on top did come loose, but I was able to fix it quickly with a dab of superglue. She slips them on and off all by herself, which is perfect as we’re still learning to tie laces. All in all, a great purchase for the price—especially since kids grow so fast and put their shoes through a lot!
