Mr. Hobby Mr. Epoxy Putty Super Lightweight Type PT121

A two part epoxy putty by Mr. Hobby. This is the best choice for use as a filler to reinforce the inside of models as it is very light and easy to cut after drying. 3 to 4 hours to dry, and it can be cut 1 hour after moulding. It is much easier to cut than Mr. Epoxy Putty High Density Type.
