I just purchased a battlemat (Chessex) and was curious as to what brand of markers you use so that is dosen't stain the mat and dosen't bubble up and not stick? Mainly I ask because I'd like to use this tomorrow and don't have time to order markers from Chessex, so I figured I'd ask. I have a Staples and Office Depot office supply store in my area so if you know of a good brand that you use that is safe and shows up on the mat, let me know please 
Thanks very much
