Mystery item

[REDBLADE_TTV]

So I was wondering if anyone knew what this was, I have an item called white boxes when I first placed it down it looked like a black pole but when I left and came back it was invisible I ended up finding scrolls and I accidentally clicked on the pole and they were attached to it and I couldn’t grab it, please help me understand what this item is

Hey there, I am not entirely sure what "white boxes" are... What server are you on?

I believe it may be furniture you are looking at, it is essentially a cosmetic for your builds. Even if it's not furniture, it sounds like something that the resource pack (/resourcepack) could fix.

Hope this helps!
