Hi Kevin - they are a hard plastic, with good detail. Only problem is the way they have been made the shoulder and the shield has a large amount of extra plastic - but it will soon be removed along with the seam lines.
The set contains 4 sets of 4 different soldiers so could make them into 2 or 3 different dioramas - you know I like my history, so we will see what comes of this. If nothing else its another sale for Monk Bar Models and more for the shelf of shame in Walkington - hohohoho
