My grandchildren handled the red poker chips from the metal box and we played a counting game together. I had no idea that the chips would run red literally all over my sofa throw until after they went home and I noticed the reddish stains. Of course, I began to fret about the transfer of dye to their hands- possibly their mouths and the toxicity to their young bodies. If anyone knows the composition of these poker chips, please advise me. The metal case is quite heavy with all the chips inside and it is a home use poker set about 20 years old that cost about $50. I hope someone who knows about poker chip composition can help me. Thank you.
