ReQ: Shulkers In Shulkers
by RemyEliot
ReQ: Shulkers In Shulkers lets a player put a shulker box inside another shulker box on Fabric, for a single item slot that holds a whole stack of boxes.
What it does
The mod changes how shulker boxes are stored in inventories so one shulker can hold another. Items and blocks stored in nested boxes travel with the outer box when it is moved, placed or broken. Files are published for Fabric only, and the mod is built for 1.21.5 alone, with the 1.0.0 file dated 2025-05-17.
The mod belongs to the Transportation category, with secondary tags for game mechanics and storage. Installation is a single file in the mods folder: press Windows + R, type appdata%, then locate .minecraft/mods and place the jar there. Client and server both need it, so the server and every player must install the same build. The mod is released under All rights reserved and is not open source.
Key features
Nested shulker storage
A shulker box can be placed inside another shulker, letting one stack hold several boxes of items.
Contents move with the box
Items inside nested boxes stay with the outer shulker when it is carried, moved or broken.
Transportation focus
Moving bulk storage between chests, farms and sorting lines becomes simpler when a single box carries a full set of contents.
Storage tidying
Fewer inventory slots are needed for bulk items, which reduces clutter in busy storage rooms.

Use cases
Hauling stock
A player can carry the contents of several shulkers in one hand by nesting them and moving the outer box.
Compact storage rooms
Nested boxes keep bulk items in fewer slots, so a storage room needs fewer chests.
Who it’s for: Players who use shulker boxes for bulk storage and server owners who run survival or transport-focused worlds on 1.21.5.
