This is the second version of the "WunderBlock"
While keeping the "WunderBlock - Soft - Fast Wearing" block we also have had the needs and requests to have a harder and slower wearing block...
These blocks have been tested, and after 1 month, "WunderBlock" is still able to be read on the plastic.
This harder block is ideal for high wear herds, or cows that need just a little extra time to heal.
