This is a tri-fold tool case, where two of the panels have open vertical pockets and the third panel is a zippered pouch. When closed, the case is about 8" tall and 5" wide.

The unlined version will be slightly smaller than the lined version; the rolled hems use 3⁄4" of seam allowance instead of the 1⁄2" of a regular seam.
