How to get rid of Winter Sale 2019 - Event Sticker?

Try writing support Steam.

You currently cannot get rid of those things. I asked steam support once about such items and they told me that they cannot delete them for me.

Besides that Bugs / Suggestions is for steamgifts not for steam stuff. You may want to edit the category (green button in the top right corner).

why did u get them in the first place?

I thought these were one-time emotes that you used and then they were gone?

It will be removed on February, but I don't remember the day.

I have the same trouble with those goddamn pigs...

You could try writing to steam support,

Although I do have one question. Is there any specific reason as to why you want to get rid of the sticker/s? If you don't use them they don't really do anything, so why the need to get rid of them? Just curious

I would say that we shouldn't really need a way to remove the sticks and emoji's, what would be better is if we could simply hide it.

This can be handled in one of two ways.
1) The selected sticker/emoji could be hidden from the dropdown when chatting and still be displayed in your inventory.
2) The selected sticker/emoji could be hidden from the dropdown and the inventory (maybe add another tab for hidden inventory items).
