Shipped in a proper objective jar, packaged in a bubble-lined envelope.
The objective appears to be in a single solid metal casting
and appears undamaged, but cannot focus in my AO 120 infinity microscope.
FWIW, also cannot focus in (finite) Optiphot; return requested.
Front optic is recessed about 1mm into the casting.

I tested further by holding it backward for far distant view (nearly infinite).
Good infinity objectives can focus a far image on ground glass
at nearly their working distance, but this cannot focus at any distance.
It nearly focuses when touching ground glass, so negative working distance?
Optical elements may be shifted inside, but I sense no looseness.

The edge of the front lens was cracked, but testing did not affect imaging.

Damage appears no worse than in eBay images; it easily passes monitor subpixel viewing test.
In the Optiphot, it is neither fully parfocal and parcentric with the BD Plan 60/0.80,
and contrast is noticeably lower, but an acceptable trade-off for sustantially increased working distance.
