This listing is for ONE Foldscope microscope kit. I have these in red, blue, green, orange and yellow mesh bags. Bag color can be specified as long as I have the desired color. When I run out of a color I will substitute another random color. I have a total of 12 of these. All new. I will sell all 12 for 0 with free shipping, or individually for listed price. Shipping to USA only.
