Good looking marbles, best advice I can give is get them off the black bottom and onto to something white whether it be sand, fine gravel, or frp panel if you really want them to show their true colors. Black bottoms will kill marbles looks and if left too long will almost loose their pattern completely. I always loved the look of that marble/motoro
Ur the second person to give me that same advice so ill have to take it. Theres an 8'x3' sitting right next to this 300 there going in soon without a blk bottom. How long for the blk bottom to be detrimental to their color? I like keeping them dark for the contrast but dont want them to lose color.
