Hi Tim,
Maybe try a couple of raw low grade beaters of commons,and see how he treats them,and if he keeps or loses interest.If he keeps interest,maybe pick up V/G graded T206's and see if he likes the idea of the plastic holder (would of course be safer on the card

).........you know kids can be rough on things,and I guess this is where the slab makes sense!!!
Hope you're doing well Tim!!!Always great to see you posting!!
Sincerely,Clayton
Let me know,I think I have a raw beater I can send you so you can test the waters
