Tarquin OptiDie Dice (Single Numerically Balanced D10 0-9)

The dice seem fine and of good quality but I failed to read the small print and only one of the dice is supplied for the price. My fault I guess , although it would be better if the seller had clearly stated in the title that this is for ONE dice so that people can compare their product against the very many other sets on Amazon that include multiples of dice for similar or even less money. I had thought I was buying 5 as pictured and didnt bother to read the full description as ..... well its a dice ..... I needed them next day so opted for what I though was 5 for a slightly higher price than a set of 12 that were a 2-3 day delivery. I contacted the buyer who replied saying its in the description but didnt offer to amend their listing title to make it clearer for the future ..... I wonder why ?!
