Just adding to my UK pen test, dont laugh....Asda laundry marker....

The Asda laundry marker with 24 iron on name tags, 75pence, bar code
ends 09851 in you local asda now.

Also add to this the lumocolor cd/dvd black, its not as good as the
laundry pen, which I found odd, I was expecting it to do well and I;m
not impressed.

I still have to find anything to beat the uni paint pen px203, which
can be left in acid virtually overnight.........
