What's considered a reasonable price for these? I could only find y2 klay for $18 per block on fibreglast. A bit steep for me, especially with shipping. Though it does look awful nice...I cannot claim to speak from my own experience, but from what I've read, Chavant Y2-Clay should work for you. Plastiline Sculpting Clay comes in regular and hard, and should also be good. These clays are all reasonably priced, so you could buy 500g of each to try.
