"As fabric markers, they work fine and the kids had a great time with them. Major pro: they're not paint and are thus much neater. Minor con: like any marker you try to use on fabric, they get gripped by the fabric if you're not careful so it's hard to draw anything with fine detail. But since we knew that and warned the kids (and b/c they are 3rd graders who think big anyway), no one had any problems with them and we were satisfied with the product."
