That said, I'm absolutely delighted that toilet brushes can be rebristled, and sad that it seems there isn't any place in the US that does this. It irks me that when a brush is retired, a gigantic chunk of plastic heads into the landfill. I have yet to find a low-impact scrubbing solution, and rebristling with some organic-origin bristle that breaks down amending the soil would be ideal. I'd pay 2-3X the cost of a normal throwaway plastic brush to mail in a brush head and get back a rebristled brush head, and wonder if the rebristling could be automated.
