Its definitely NOT the pink Marb. We used up the surplus pink marb from last m25 at a recent training session against ourselves and ALL paint marks came off our clothes and off the supair afterwards. The staining stuff at M25 did NOT come off the sup'air! Can't comment on clothes as I didnt have any stains on clothing that didnt wash out so either a) I didnt get hit in the games against those teams using the paint or b) Tsunami didnt play them!
I think I recall Sparklie saying this stuff also kills the grass so our Chairperson did some tests using our Marb, just in case... test results negative!
RPS Rocks! Perfectly round and eco-friendly!
