There are some things in this game that just grab you.
Sometimes you try something and suddenly wake up to the
matrix you've been living in - in this case the matrix of the toothbrush! 
Apart from all the plastic we are throwing into landfill with common toothbrushes,
until you use a natural bristle you won't know what you are missing.
Nylon has a shear shaft, natural bristle has nodules
that in turn actually clean your teeth.
There's no going back for us, we now know what real clean teeth feel like.
Made in Germany by very clever environmentally friendly types
NB these bristles are made from Boar bristle, a by product of the meat industry - for our vegan friends may we suggest our 100% bamboo can find it  here
