I am disappointed, I thought they were different sizes and bigger than what they were. I am guessing that the blue one is for the refrigerator because it said there was only 1 for that. No real instructions came with explaining anything....I just got them today so, I am placing around my house and will update in a few days to see if they really work.....🤞🏻
I love how it took care of the smelly cabinet under the sink in the bathroom. I got 7 of these so I put them all over the house. In the bathroom, in the closet, in my grandson's room. I love it so much I ordered another set to give away to my daughter. I recommend this product.
