These are just some crappy office supplies, 2 eur each, with holes drilled through their bottoms with a sheet metal drill bit in an electric screwdriver. I am looking at buying clay and firing it myself, or casting geopolymer lye/clay/cat litter crystals, containers are not just expensive, there is no place that sells them locally. I might become local bonsai evangelist if I step over my imposter syndrome (well, I am one, I suppose) and get non-negative balance on my bank account to start something.
