I thought that this ink was very expensive till I bought my first bottle. I think right now it is my favorite ink. I just went to Europe and bought three more bottles in different colors. It flows so nice and smooth. This color purple is my favorite. Plan on buying as many bottles as issued that I can find. Worth every penny.
You will keep loving many more beautiful colors that Montblanc is offering. We already are a big fan of Montblanc petrol blue ink .
I've used this ink with the corresponding beatle's fountain pen with a medium nib. This ink color is deep enough to be used in business and light enough to have fun over it in a meeting with clients or colleagues. The ink is not wet at all and it tends to dry quickly. So far I've used it to write on TOPS yellow pads (which I think is one of the most expensive brands if not the most expensive yellow pads in the market of regular paper). However, I have noticed that the ink feathers when used in the most expensive pad there is: TOPS Docket Gold Wirebound Item #99703, but it doesn't at all when writing on TOPS yellow pad item #75324 which is not wirebound. Go figure!
I've used this ink with dip pens for daily writing of notes for my kids. I've also used it in my Visconti and Pelikan pens for daily writing of work notes without issues such as bleeding through paper (I use fine nibs), cleaning in my pens didn't have me spend tons of time cleaning. The glass bottle is a nice piece that fits well on a professional desk and easily fills my larger Visconti pens. Although it is called "The Beatles Psychedelic Purple" the bottom of the bottle says "encre violet" which translates from French to English as "ink purple" it can be compared to both Purple and Violet inks out there.
