Apple 21.5" iMac Intel i5 2.9GHz 1TB

This description is very misleading… It says:

Apple iMac MD095LL/A (Late 2012), 21.5" (1920x1080) FHD Display, Intel Core i5 3470S 2.9GHz, 16GB DDR3, 1TB SATA, 802.11n, Mac OS Sierra

It says 21.5" but the product number: MD095LL/A is the 27": and then further down it says: 27" and core i7.
Anyone know if it is the 21.5" or 27"? Thanks!
