Beware, there are loads of sellers claiming they are selling TAOM Chalk, it is fake!!!!! The cheapest genuine TAOM V10 you can get is £15. The fake green is a darker colour, the lettering is not quite the same as the real thing, some fakes do not have any writing on the base, if it does, check the word Registered, fake ones are misspelt (Registeaed). Genuine chalks have 4 packaging marks on rim of base, fakes have five. TAOM lettering is smaller and slightly different on the fake. The Green V10 on the fake has a narrower V and is a darker, less reflective green. The writing and Lion's head on the base of the genuine chalk is far more reflective than the fake. Also, on the genuine chalk, the Lion's head on the base faces towards the centre of the V and T
Basically if its cheap, its fake.
I'm surprised Ebay is allowing this fake product to be advertised and sold on their site.
