You have a good friend and wanna give him a present? This present stand is right for you! Just right click with the item on the present stand and it will be rendered above.
This is mainly for birthday or christmas. Or you can just use it as a block where you can show your best items! And if you're playing with an texture pack, don't worry - the block will adjust to EVERY vanilla texture pack.
EVERY single color has its own present stand now!
You're allowed and it is recommended to use this mod in modpacks. Because if you will play alone this is only good for show yourself your best items.
