Here is something that is for sale today. Interesting:

I know these ones work because my mum uses them but you would spend lots of $5.99 as they go missing and aren't that durable.
Can't wait until we get into that market, so much potential, I will personally be buying my mum heaps of them as she is a nightmare to go travelling with.
