I'd recommend this (I think that's the size, but I'm not sure) for an overall mix of price, utility and form. It holds most of a 12oz bag of beans and keeps it without a noticeable drop in flavor for 10ish days.
The marginal reduction in air exposure from an Airscape compared to a traditional airtight container isn't necessary in my opinion, but I frequently enjoy McCafe beans so what do I know?
I've bought these Bormioli Rocco Fido jars to store coffee beans in. I've had them a couple of years and they've held up so far, but I can't vouch for them being BIFL quality. They come in sizes up to 5 liter.
I can easily fit an ounce in mine and would feel comfortable walking next to a cop. Bormioli Rocco Fido Clear Jar, 25.25 Oz. https://www.amazon.com/dp/B0001BMYGG/ref=cm_sw_r_other_apa_2tUPybNJB1VBF
