The Brush Dock toothbrush and toothpaste holder is made from aluminium and is powder-coated in hardwearing, long-lasting paint.
It suits manual, handled toothbrushes (whatever they are made from, and is especially good with bamboo). They simply hang in the small side slots. 
You can choose a dock for two or four brushes plus one toothpaste in the middle.  It comes with a suction cup for mounting to smooth, non-porous surfaces. 
The toothpaste tube simply slides (cap to the top) in and out of the centre of the Brush Dock.
 
This Dock comes by with a pvc suction cup for mounting to surfaces that are smooth and non-porous (acrylic, glass, mirror, vitreous china, many smooth tiles but not all).  Wet the back before adhering.  Suction cups won't stick to rough or porous surfaces, like textured tiles or paint because they can't form the vacuum needed to work
