Prepara Guac Savor Airtight Food Container for Fresh Guacamole – 4.5 Cups Capacity, BPA Free, Compact Kitchen Essential, Dishwasher Safe

I am pleasantly surprised that this works exactly as described! I put one avocado worth inside (there is probably room for 6-8 depending on size) and pushed the lid down very tightly and 24 hours later there was not a single brown spot. No amount of plastic wrap and airtight containers and lime juice has worked this well for me before (and I eat a LOT of avocados). My only concern is the tiny holes on the inside of the lid will be annoying to clean. The lid does come apart so you can access from both sides so I think my dishwasher will handle this part.
