These Work Well [SEP] I make my own hydrogen peroxide based laundry stain remover, which is sensitive to light, so these bottles are perfect! The bottles themselves are nice, thick glass and come with a sprayer nozzle for each bottle as well as screw on caps and cute chalkboard labels. The sprayer nozzles feel a bit cheaply made to me, but they do work quite well. I would like to see the tops be made of nicer plastic, but for the price, I would recommend these.
