egg tray type

Which egg-holding form this egg tray is — a token from EggTrayTypes: an open tray (the uncovered stackable filler-flat) or a lidded box (the enclosed hinged egg box/carton). A category discriminator (an open 30-egg tray and a lidded 10-egg box are different products/listings, never buy-box versions of one another), so grouped_in identity and non-axis-eligible — the utility_vessel_type / waste_bin_type identity-fold pattern.

Egg tray type is answered with one word chosen from the egg tray types list — the same word shared across every product that uses it.

It belongs to identity — who and what it is.
