Client Glitch: How to self gift mystery skins

I already forward this glitch to riot support In order to do this you need to follow the seven steps below

I found a way to mystery gift yourself without one those self mystery gift sales. This is the process I went through to self gift.

1. play a ranked 5 v 5
2. once the match is over go to your profile tab
3. click on your rank team you just played a game on
4. go to history and click on the game you just played
5. click on match details
6. click send gift on your name
7. you can now send yourself mystery gifts.

Some things I noticed the game has to be relatively recent, the match needs to be less then a day old, in order to mystery gift yourself. Your RP amount does not update until you click on the store however the game will not let you buy something with less RP then it is worth. I don't know if the same process works with 3v3's You can still gift yourself once you log in and out
