for long periods.

"VTT (Versatile Training Tissue), developed by KOTOBUKI Medical over the past four years, is an innovative medical training organ made of edible ingredients such as Konjac potato powder.
The simulated training organs already on the market are often made of silicone or plastic, and medical training with energy devices has not been possible because they melt at high temperatures and friction.
In this respect, VTT has a tactile feel, strength, and elasticity similar to human tissues, and can withstand high temperatures.

By changing the composition and manufacturing conditions, we can freely control the strength, hardness, elasticity, and color of VTT. We also can control the shape unlimitedly by using the resin mold made by a 3D printer. We accept OEM products, and we can match your any needs.

Since it can be stored at room temperature and for long periods, you can train at any time regardless of place and occasion. Although it's on an experimental basis, it's been successfully stored for more than a year after the production."
