Rather than throw the bottle away when the brush gets worn or you lose a cap, you can get replacements here. We also sell in wholesale quantities at much cheaper rates for one or more boxes of 1100 units. When you get the cap, the brush is hidden into the cap. You’ll only see the brush after you have screws the cap firmly onto the bottle and this locates the brush that is inside the cap. When you then take the cap off you’ll see the brush neatly located on the bottle.
