Can't sell Garry's mod Tshirt, why ?

I got 2 Garry’s mod Tshirt, but not able to sell them, why ? :frowning:

It’s 100 euros for both :confused:

How did you get them?

I had one by playing the game, and just trade with a random idiot german tshirt for G’s tshirt lel

I told him it worth 46 euros actually, he insulted me x)

You should really post in the GMOD subforum.

The one you traded might have a week delay before you can trade, but I am not sure about the one you got in game.

How does this relate to Garry’s Mod?

It’s a gmod tshirt and maybe a gmod dev or player would like to purchase it i guess
