150mm PVC pipe, capped one end, screw cap on the other. PVC cement a couple of lengths of conduit (PVC conduit of course) on the inside to help the contents tumble, rather than slide. Watertight, works a treat
This was the cheapest I found:
Kontiki coulper with thread rubber seal cap-150mm | Trade Me It has a big rubber O ring on the inside, I run a little dishwash on it before I screw it up, helps make a good tight seal, and also helps release it when it's done
..and a 150mm 'push on' cap from the same place. I have a length of plain 150mm pipe ( to go between the fittings, only need 80mm so not worth buying a meter..), and a meter of the conduit you can pinch if you're in Auckland. PVC cement from the Warehouse is a couple of bucks.
Total cost around $50 and it's bullet proof.
