Crystal wall 1x1

is a buildable structure. It requires Crystal to build and needs to be built within the range of a Workbench. Crystal walls are useful for making decorative windows (or even a greenhouse of sorts), but care should be taken as they are very fragile. As they provide no support of their own, they cannot be stacked off of each other directly, unless other structures are used to support them.
