Blister contains 20g of Citadel Modelling Putty (Green Stuff).

This is the same putty that the Citadel Design teams use to make our models. If you're up to the job, it can be used to remodel features or make your own models from scratch. Green Stuff is also very good for filling gaps in larger mulit-piece models. It is very tough once set and can also be used to attach pieces in some situations - for example, fixing riders onto horses.
