Effective minimalist deodorant for sensitive skin

I've tried lots of "natural" deodorants that have given me skin rashes. I suspect that I have a sensitivity to bicarb soda but I'm not sure. I took a risk with this alum stone and am pleased it has worked out. No skin rash despite regular use; no oily patches on clothing, no scents/perfumes, and no essential oils. This buy will last me years and is easy to travel with too since it isn't a liquid or cream, Easy to store, low waste, plastic-free. Great buy.

Great packaging, poor result

Chose this item to reduce my plastic packaging. Poor performance, even when based at work, strong perspiration and odour. I have stopped using it and wouldn't recommend it. Only gave it 2 as I thought the packaging was good. Tried no pong and had a completely improved result.
