Like some other Copic rookies I've seen online, I accidentally purchased a set of Originals instead of Sketches, and sorely missed the Super Brush nibs. I ended up replacing most of the chisel nibs with these! If you're anything like me, you're probably reading this wondering how these nibs compare to the Super Brush. They're pretty close, but don't quite produce an identical result. They're a fair bit smaller and shorter, so you can't achieve the same wide stokes as the SB nib, but you can get more precise with them, so it's a pretty equivalent exchange! They're very easy to install as well. All in all, an excellent little nib!
PS: If you're outfitting a whole set of Originals like I was, I recommend buying all the nibs you need in one purchase. I did it over several months to ease the hurt on my wallet, but they ended up running out of nibs halfway through the process. They're significantly more expensive elsewhere, and it took months to restock them, so if they're in stock here I advise buying quickly! Happy sketching!
