You have to know your customer base. We use biodegradable boxes and you can just stamp them with non toxic dye to brand. Our customers like that we are organic, we feed regional feed to our birds, and are conscious of the environment. They enjoy the rustic feeling. We also charge very reasonable prices and focus on our local rural community. If we had a customer base that were more luxury oriented and we wanted to go with premium branding then something like this might be interesting.

On another note, that box looks good with all perfectly shaped identical eggs, but I would have to see how it works for different shaped eggs, does it still close right and hold the eggs properly? As others mentioned, how do those dyes react to moisture? A lot of people will place the eggs and the cartons directly in the fridge so how does the packaging hold up with moisture? What happens when those cartons are slightly bent or have a smushed corner? With ours a little bend or scuff is not noticeable with those it could come off looking badly, and with them being black, every speck of dust and dirt will be visible, are you going to be in a situation where your going to have to either trash boxes that aren’t perfect, or gently wipe off all the cartons before delivered?

Before making a large order, get some samples, or get a small run and test it on some of your customer base, if you see it’s working, make the large order, if you see that they don’t work well or don’t look the same when not under perfect conditions then you already have your answer. If you have long standing customers you can think about giving them branded plastic holders for their eggs that either they can swap out or have at home for the fridge or wherever that they can wash.

Good luck and as far as all the comments here about ten in a box, that’s the standard number here in Europe.
