Milliput White is a fine epoxy putty, ideal for detailed work and small parts. The single item comes in two 56.7 g sticks that must be mixed in equal parts. Once mixed, it can be molded for 90 minutes before hardening, although this time can be reduced by applying heat. During this period, it is easily worked with tools moistened with water, allowing smooth surfaces to be obtained.

When hardened, this Milliput putty can be sanded, cut, drilled, and painted, making it extremely hard and resistant. Other advantages include the possibility of adding layers, non-adherence to tools, and the option of delaying hardening for up to 24 hours by storing it in the freezer. It withstands temperatures up to 130°C and can be mixed with play dough, although this reduces its hardness.
