I agree, it's very nice.

But a surprising part is, there's only one place that prints them. You'd think with how easy it is, the market would be full of various inventive designs. But I scour high and low, across all sites, and this is the only one.

Many people print containers of various kinds, but all of them must be operated with two hands, or at best are extremely awkward and unreliable when used with one hand.

How comes that in this vast nation only one man has the right idea. It cannot be.
