Grin Jack

Real enough that people flinch
-
Sculpted by pro FX artists

Breathable latex - no heat - no fog

Grin Jack began as a simple jester.
Then the smile changed too wide, too still, too deliberate. What was meant to entertain slowly became something far more unsettling.
Once you see the grin, you can’t unsee it.

- Each mask has subtle variations, making every piece uniquely its own.

- Open eye and mouth areas provide visibility and airflow while worn.
- Lightweight construction makes it suitable for parties, events and Halloween nights.
- A mild latex scent is normal when first opened and will gradually fade after airing.
- After use, gently wipe the inside and allow the mask to air-dry completely.
- Store away from heat and direct sunlight to preserve its shape and finish.

I created PersonaLabFX because I never wanted to create ordinary costume masks.
Around me, a small crew brought each character to life: Michel shaped the molds by hand, Jack carved the scars and teeth, Sarah painted the shadows, Olivia aged the latex, and Maya added the final unsettling details.
Every mask was made to feel like a character, not clean, not friendly, not perfect.
Our team is now moving on to new film and creature projects. Once these final pieces are gone, their molds will be retired.
That is why this last run is priced lower than usual. I would rather see these masks worn, filmed and remembered than left hidden in the workshop.
Not costumes. Characters.
Once a design sells out, the nightmare does not return.
Each mask begins with a sculpted form that defines the expression, scars and features.
The mold is created, latex is cast, then layers of paint and aging details bring the face to life.
From raw form to final character.
Tested. Terrified. Approved.
Definitely go for the full set. The mask is great on its own, but with the complete costume it’s on another level. Huge success.
The quality surprised me. The mask feels solid and the details look even better in person.
The full set really makes the costume. It looked much better in person than I expected.
The quality is there. The latex, paint and overall shape all feel much better than the usual costume masks.
The mask is already creepy, but once you put the full outfit on it completely changes the look.
People genuinely backed away when I walked into the room. Grin Jack gets a reaction instantly.
Way creepier in person. Love it.
The paint and facial details look much better up close than I expected. It doesn’t have that cheap costume-store feel.
The teeth are my favorite part. They make the smile look completely wrong in the best way.
Bought this for my husband and I honestly hated seeing him walk around the house in it 😂 Exactly what we wanted.
Way better than I expected.
Definitely one of my best Halloween buys.
For the price, I honestly wasn’t expecting it to look this good in person.
Much more detailed than the photos.
Really happy with it overall. Would’ve been perfect if the shoes were included too.
Grin Jack looks even better in person.
The teeth and the expression are what make it. Super unsettling.
Didn’t expect it to feel this complete straight out of the box.
Very good overall. A shoe option would make the set even better.
Exactly the kind of creepy jester look I was going for.
The costume really completes the look.
Looks great and fits the character perfectly. I ended up finding my own shoes to finish the look.
The outfit has a nice loose fit and looks great with the mask.
Once the costume is on, the whole Grin Jack look comes together.
