jesmonite
JESMONITE®is a composite modeling material consisting of a reactive mineral base and pure water-based acrylic resin.
Although Gesmonite is a resin, its texture differs from that of conventional oil-based resins. It is a material with a calm, stone-like texture with almost no shiny feeling characteristic of plastic. It can be used to create three-dimensional objects for a wide range of applications, including art, sculpture, furniture, interior decoration, displays, accessories, and architecture.

Workshop open to children and adults!
The process is simple! Simply mix the prepared special liquid and base (powder) for about 10 minutes, add your favorite color, and then pour it into the mold!
*A staff member will be on hand to assist you throughout the entire process, so even first-time participants can feel at ease.
Wait for about 45 minutes in the same state, and it will be completed! When removed from the mold, the world's one and only onion objet d'art is complete!
*We recommend that you enjoy lunch, shopping, and photo spots in the facility after pouring the molds!
Comments from guests who have participated in the program
I enjoy mixing colors! Whenever there is a workshop like this in my travels, I always attend!"
"I got some color on the bottom, but it was hard to get a nice marbled look!"
My daughter turned out beautifully marbled, but I got all dyed [laughs]."
I'm glad it mixed so nicely! And I'm glad I can unmold it myself!"
I felt it might be difficult to do it alone, but it was fun to color it so beautifully!"
I love picking out the colors!"
It was fun to be voracious and blue!"
I found myself mixing too much, kinda hard!"
All of our staff members sincerely look forward to seeing many of you there.
