I use a lot of material, that is why I have created a hobby-box out of a toolbox.
In it you may find all sorts of clay (and in different colours), extrusion gun, kitchen knife, lids, spatulas, wire, varnish, rolling pin,  shade tex.
It is now easy to find the right tool or clay colour.

Some examples of Fimo packages.

This set contains pieces of clay of 25 gram.

The usual size is 56 or 65 gram!

An example of a Creall-therm container.

The rolls weigh about 150 gram.
