It would be really nice to do it.

You should expect exclusive items on full release. One for example was the spooky eyes. It was a Halloween event face that is still on sale but would not be if this was the full release of ReeliChat. Since ReeliChat is still in public testing, many things will change and many things will be added on full release. Hope this clears up any questions.

no point of exclusive items if every item in the catalog gets removed on the release

Everyone is wearing faceless face lol
