One of only 4 eldritch opening demo hats, one of 2 non-quickswitch misc eldritch opening demo hats.

Only sale in over a year.

The other eldritch opening elf esteem is still in the inventory of the collector who unboxed it.

Compare link is busted, I quicksold the blizzardy storm sensei to mockingbird for 59 keys then immediately paid 70 keys for the eldritch opening elf esteem.
