Interesting set. I, personally, won't be going for it because, in my view, it's too expensive for most of the items.
The only one that's remotely interesting to me is the glass dip pen. That price is comparable to ones you can get stand-alone. The others though, you can much cheaper make yourself or buy in pieces.
The main one I'm talking about, at least with my experience, is the brush set. Honestly, I strongly recommend *not* buying that, for a few reasons. First, the quality of the brush is pretty awful. It doesn't nearly come to the tip one really needs. Meaning, unless you're writing fairly large characters, then brush won't be great. Given you're given 1 sheet of paper means you'll do around 4 characters comfortably and that's it. You can't use this brush and ink on Rhodia or anything else really easily. The ink will be an issue. So, if you're interested in putting together this specific set, I suggest you go for something like a beginner brush (about $5 at an art store), and pad of calligraphy paper (rice paper, comes in sheets in some, single roll in others - about $20), and either pure Sumi ink, or India ink. India ink is considerably cheaper than Sumi ink. If you get liquid ink, you can pour what you need into a bowl and go with that. Better yet is an ink stone (about $15-20ish), so you can better control the amount of ink on the brush.
I'm including a picture of some of my specific setup. Not all the brushes I have/use. I kept one of the cheaper practice brushes in the picture (the one on the right). The two on the left are used for different things, and are much more expensive than I recommend people who are just getting into this. You can find decent brushes on Amazon, that don't run much.
Alternatively, if you're really interested in 書道, I recommend getting a brush pen instead, and use grid paper to practice characters. I've done this extensively while learning Kanji, and it's useful for learning the balance of a character.
