I purchased 2 of these nibs, save your money and stick with the originals tips the ultras came with. These things are so flimsy and weak. They fall out easily and writing with them is like using wet flatten cotten.
Props for trying to get close to the original, but these nibs are useless especially for $10 a pop.
I'll still continue on buying your other products but can you credit me back my money on these things? I bought 2!
