Description: 

This putty is specially designed for models using ultra-fine microballoons.
Ultra-lightweight finish due to the use of urethane-based balloons.
Easy-to-sharpen hardness and fine finish. Indispensable for balsa kit production.
Even after fully cured, it is almost the same hardness as balsa material, so sanding can be done easily.
The color is brown, very close to the color of balsa wood.
Before hardening, if it becomes dry, add water and knead to return to the initial state, so it can be used until the end.
Made in Japan.
