IMO WB tips have changed a little over the last year. The box in the picture looks black, which is the Hard WB tips. The Dark Brown Box is the Med-Hard tip. They now are very shiny and looks like they have a coating on them. They used to look rougher, with no coating, like the one on right. I think Atlas sells the Black box (Hard) and J&J sells the others. Love this tip Med-Hard for play, and Hard for Breaking. I have put over 10 boxes of these tips on over the past 9 years, and sold some of them also in ebay. Not an expert, just a user.
