Aladdin, towards the later part of his life, and we discussed the different ways if stalling the dice problem. We agreed after all that was tried that there was no fix to the destruction of old dice.
One thing we did agree on was to us a lite spray of clear fingernail polish. The brush on would get in to the color and start to dissolve the design. Bad to much, same, Bad. But, it was better than brushing. once they implode there gone. Sorry,
