The pine or fir looks like it is dry and ready to use.
But.....since the blocks were sealed in wax they may not be all the way dry.
A lot of the time with turning wood it is cut green then coated with parafin wax.
That is to keep it from drying out too quick and cracking.
I would be sure to remove all the wax and let them sit a while before using them. But if they start cracking after you remove the wax they were still green.
If you don't plan to use them this year, just put them on a shelf as is.
If there is a woodworker around with a moisture meter, it would be nice if they were under 12% moisture content.
