Perfect for Your Favorite DIY Essential Oil Blends.
The Blue Essential Oils Roller Bottles are  easy to use. The size allows for easy blending of my favorite essential oils with room to top with fractionated coconut oil. I have not had any difficulty with the roller balls and the lids fit tight. The blue glass is not only prettier than the clear glass bottles I have used in the past, but also helps to block the light from the oils. I would order these quality blue roller bottles again.
