Koyashiyaki Kuzo (Koyashiyaki Kuzo) Set Dosatron & Sprinkler Sinkers, etc. All

This includes everything in the Dosatron fertilizer injector set (box not included).
This is one of two sets I had; the other has been sold, so this is the last one.
I cannot offer further price reductions.

I purchased this new and only ran water through it once. I am selling it because I haven't used it since.
It's practically new, so I believe it's a great deal.
