Recently I have been playing around with the biohazard symbol from the logo (thanks again @6ft5 for help with the logo) on the capsules. For the beers I bottled fro Christmas I manually cut out stickers and glued on my black capsules. It looked nice, but a lot of work. So although the price was quite high I ordered printed capsules during the holidays from BottleMark. I chose to have yellow caps with black printing to get that warning sign feeling.
And now they have arrived and look awesome! The print really god and kind of thick that gives it a slight 3D effect. Worth the price deferentially. The first beer to get them will be the batch of Queer Zombie of Hops that I plan to bottle soon. But more on that later.
