鵝卵石/泥土斜向回填（未上色）

Finally got these to finish off my diagonal layouts, and the double-sided backfills mean I can flip them for either cobblestone or packed dirt without buying twice. They lock in tight with the existing pieces, so no more awkward gaps when I "break the box" mid-campaign.

The double-sided design is a lifesaver—flip it over and you’ve got both Cobblestone and Packed Dirt covered without needing a second set. Fits snugly against the diagonal pieces, no gaps or wobble. Glad I grabbed these before my next build.

These diagonal backfills are a perfect fit for my cobblestone set and really help keep everything aligned when I'm building out of the box. The double-sided design is a clever touch that gives me more layout options.
