Do you have any inks that you wanted to buy after reading great reviews that turned out less exciting than expected?
My biggest disappointment is Diamine Skull & Roses. After seeing swatches online I expected a blue ink with a visible red sheen. Unfortunately the sheen is just not there at all, it looks like an average dark blue ink, not even blurple. I’m glad I’ve only bought the 30 ml bottle.
Don’t know when you got your bottle, but I do recall that there were some inconsistent batches with Black Swan specifically. I have two bottles and they behave very differently, with one feathering a ton and the other behaving well.
In this case, it’s possible you did indeed get a bad batch!
