I did some trades with Wally, and everything was super-smooth!
Now i have 4 markers, and 3 of them are from Wally.
I really wouldn´t hesitate to do business with walz, dealing with him is always a pleasure. The markers are as described (or better) and the packaging could take a direct hit from an RPG unharmed.
If i ever need another marker i think i will ask wally first...
