Those plastic tubes would be ideal, but I've not found a place that sells them yet. I'll keep my eyes peeled.

For now I went to a packaging wholesalers and bought some "dipping sauce" tubs. The kind you get for supermarket sample tsting. They are about 50ml.

I dosed a bunch yesterday, writing the powder and charge on the lid.

There is a problem with static, as expected, but a small sable brush will take care of that...
