Zak Bagans to Display Jewelry Box From Dead Model Masuimi Max's House

Zak Bagans has a new cursed item going on display at his museum, one with a connection to recently deceased Playboy model Masuimi Max ... TMZ has learned.

The paranormal investigator tells us ... Charles Max, Masuimi's brother, met him at his museum in Las Vegas and was totally rattled by an innocuous-looking jewelry box he said once belonged to MM's mom.

After their mother died, Charles told Zak their father kept the jewelry box ... an odd move, because Charles says Korean people generally burn a loved one's possessions after they die.

Charles ended up taking the box, and quickly wished he hadn't -- he told Zak the box gives people amnesia, and detailed several other terrifying experiences with the creepy artifact.

For example ... Zak says Charles told him several mirrors in his house cracked when he put the box next to them, cold spots cropped up in different places in the home where Charles said he could see his own breath.

He even claims he would feel paralyzed at times, describing it as being grabbed by an unseen force.

Ultimately, Charles told Zak he gave the box to one of his sisters -- NOT Masuimi -- who swears she never gave it to Masuimi.

While the paranormal experiences stopped haunting Charles, the whole family has no explanation for how the box ended up in Masuimi's possession.

We broke the story ... Masuimi died last month at her Las Vegas-area home. Cops said no foul play was suspected at the time though her cause of death is still unclear. She was only 45.

On the same day she passed, Charles and his other sister went to her house, and found the jewelry box on the floor near the door -- again, shocking 'cause this other sister says she didn't give it to Masuimi.

Charles swears Masuimi would never have wanted the box -- she didn't have a good relationship with their mother, so there's no reason she'd covet it.

One more creepy fact/coincidence ... Masuimi died on the same date as her mother.
