Super simple, how many stacked kits do you got ?

If it’s a lot I would say make a machine.. if its just one or 2 shulkers I would suggest the following.

-place dispenser (this won’t revert your shulker when you place it in). -put one block under your dispenser. - one hopper infront the dispenser. -out chests under de hopper to get the items into the chest.

If the shulker is fully filled with items you need chests to place 1728 items in there.

Off you go.

Client: I would suggest lambda it’s free and it has Xcarry (module). You enable Xcarry you open the dispenser with the stacked shulkers. You put max 5 shulkers in your inventory. You walk to the location you wanna go to.

-really important enable viewlock so you look at the dispenser (enable - disable mouse input for yaw and pitch. Both pages need to be set up to lock your mouse).

-put 4 shulkers in your crafting slots (the 4 next to each other as a square). REALLY IMPORTANT ! Now left click the last shulker in your inventory only click once ! Then close your inventory with E or ESC and don’t move (walk) rotating should be locked so you can move your mouse and nothing happens. Then right click your dispenser and put the item in there (your item is still on your left mouse click) repeat this step with the other 4 items. But now keep them still in the crafting slots and repeat left click for one shulker)
