I already have a Jade yoga block from Galaxus and would like a second one. But mine has the dimensions 22.8x15.2x10.3. Has anything been changed?

Is this the small of the two yoga blocks? At JadeYoga itself the small one only costs 24.90. Why are they both 29.90 on Galaxus?

Why does the large block cost less than the small block? In the case of the small block, there is only 1 measure instead of all three in the title and nothing in the description.
