Comments about Sharpie® Rub-A-Dub® Laundry Marker, Black, Each:
I've been using Rub-A-Dub Laundry Markers for decades and have found that the ink seems to be more permanent and resistant to water than the standard 'Sharpie' Pen. We use a Rub-A-Dub to write ID Names and Numbers on clothing, suitcases, carry-on luggage, computer bags (and other equipment bags), shoes, briefcases, and anything else that might be washed or exposed to water/weather. It's curious that Rub-A-Dub pens seem to be getting harder to find in stores than they were a few years ago. But, I ordered five Rub-A-Dubs on-line and picked them up at the Staples store the next day (no S&H charge for store pick-up). So if you've found the standard 'Sharpie' pen to have less durable ink than your project requires, try a 'Rub-A-Dub'. It's a really good product.

Bleeds. The bleeding is the only problem bit that is the nature of material I'm working with. I would buy this over and over if there was a way to help control the bleeding.
