No doubt  .

        I never regret material or tool purchases    ;D   .

                                                      You just need to consider any shelf-life issues  .

     I don't know about it having much adhesive ability  .

       I opened this one and the Mr Clay  , did some random sculpting and stuck each to a piece of sheet styrene - pushing it thru a hole to see what I got .

     That oil-clay didn't stick at all  -  or of course harden   

         It will get used  -  I have no doubt    ;D

         

         Thanks  Hagoth
