Rapha, nice but a bit pricey?

I partially retract my statement, I did not realise it's so hard to find a fully seal-able insulated "cup", for much less than that price point, but I guess it's also quite a niche product inflating the price.

I think you could clean up by designing a lid without an opening for those "travel mugs", they're about £2/pop in bulk, slap some fancy colours on, sell it for £10, mad profit.
