These solid (much better than hollow) kalimbas are made with high quality steel made corrosion resistant with plasma coating (a fancy way of plating) with I assume stainless steel.
They sound very good, good for relaxing. I prefer the B17 and B15 for a greater variety of notes. You can experiment and find the ideal size of neodymium magnets to change the notes as needed and even make some cool sounding effects if you double some of the notes whether in tune or slightly out of tune with each other. Placing it on a table will make the sound come from the table and enhance lower notes, attaching hard objects loosely to the wood will cause buzzing, which may sound desirable in some cases and is a technique commonly used on African Mbiras.
Buying direct is probably cheaper than from a reseller.

I had never heard of this instrument until reading your post! Thank you for sharing!
I play the piano, violin and a little mandolin (because the fingering and tuning is similar to the violin). I always wanted to play guitar but never managed to get it down because it was so different from the violin. However, I cut off the corner of my pointer finger on my left hand and that makes it a bit harder to play the mandolin. I have played a little harp (because it is similar to the piano) but no more than just tinkering here and there because I have never actually owned one.
I took violin lessons for years but by itself it doesn't always sound amazing. So, I generally tended to play the piano more even though I only took lessons for half a year when I was 5/6. My siblings did teach me more though over the years and I also just learned from spending hours messing around on it and making songs. Before my sisters and I were married, it was amazing playing the violin with them. We used to have our own trio! We had 2 violins and a cello and would play Bach, Corelli and other amazing songs. Great memories! I rarely have time to play any instruments now with the little boys around. They always want to "get in on" any excitement...which means wanting to play the violin if I bring it out etc. But...They aren't quite old enough to have the patience for lessons. The oldest is getting closer though. Hopefully one day I can teach them and we can play together! 🥰
