so something that blocked out the light does not guaranteed to block out uv then am i correct? and actually the one I'm using is not the exact one as depicted in the picture it's actually blue anyway thank you very much for your reply

I would like to know if i store some uv sensitive stuff or something that could be degrade in the long run by uv rays in these kind of containers http://ace.imageg.net/graphics/product_images/pACE3-1415657enh-z8.jpgcause some of my friends told me that if the light can't shine through then uv can't get through as well is this true? thanks a lot and sorry for my english im not a native speaker Nook
