Build a Glass Box

Create a hollow glass enclosure instantly

✅ Verified for Java 26.2 · Bedrock 26.32 — checked June 2026

Creates an 11×6×11 hollow glass box — instant observation dome, mob display case, or greenhouse shell. The hollow keyword builds only the shell and clears the interior, so anything inside stays visible and contained.

/fill ~ ~ ~ ~10 ~5 ~10 glass hollow

How to use

  1. Open chat (T on Java, / on Bedrock).
  2. Move to one corner of the intended box.
  3. Paste the command and press Enter.
  4. The glass shell appears with the interior hollowed out.
