Our Basalt stamp is modeled after the famous Giant's Causeway. It is a great texture for any of your volcanic or shore line related models.
Our stamps are made in the USA from synthetic rubber similar to tire rubber. The size refers to the actual texture area. They are perfect for making themed artistic bases that only look like you spent a lot of time or money on your project.
The main sample is stamped on a 50mm base with 'green stuff'.
