grog is the only ink i buy, it is absolutely great in every since of the word, it bleeds through, drips if you want it too, dosent drip if you dont want it, and is very very hard to buff. i remember buying grog when it first came out and hating it because of the smell (at the time i was a toy in bathroom stalls haha) but when i bought it again i actually learned to really appreciate such good ink. although grog does owe me a few hundred dollars in clothes haha.
