We make our models from a carbon and resin infused, diestone composite material which has a compression strength of over 17,000 pounds per square inch which makes them very solid and suitable for literally years of use.
With that being said, our models are not indestructible and can be chipped or broken if severely abused or dropped onto hard surfaces so we generally recommend our models only be handled by teens and adults.
All sets purchased from Dungeonstone as "pre-painted" should be considered as custom works and as such there may be slight variations in the color or appearance from piece to piece or from set to set. This is normal and to be expected.
