I had bought the 12-egg cartons for my quail eggs and did a repeat order for 15-egg. Unfortunately these don't fit my coturnix quail eggs. Bummed because I ordered 150 assuming they would fit the same size as the 12-egg carton. After, I did note that the cell dimensions are smaller based on measurements in the description, so that was my error. 1" x 1.5" is the measurement on the 12-egg and 0.875" x 1.625" are the measurements on the 15-egg.
Eggcartons.com was responsive to my message and we're looking into the plastic cartons to see if those will be a better fit. Struggling with removing a star because they are a great company to work with... but I think if these are being advertised for quail eggs there should be a disclaimer that they may not be a fit for coturnix quail eggs. I'd really like to stick with pulp over plastic.
