THIS is a Wonderful investment whether you are an adult or for your kids! $3.99, does not include the 4 AAA batteries, but this is a good deal for taking a closer look at your fossils and for prepping!
The plastic visor is adjustable to almost any head size with velcro in the back. The visor flips up and down. The main window doubles your magnification. The little loop is about 10x magnification. The lights are indiviually operated on either side and really add to what you can identify.
This was regular price at Harbor Freight. I wish I would have known about this a year ago!
