Go to Rust Labs to find the Workshop ID and post the ID number here or send it to me over steam as a private message.

https://rustlabs.com/skin/training-hoodie

Make sure that the skin is not already in the SkinBox by opening it with the command /skinbox in chat.

If you want to make it easy for me to copy and paste send it to me in this format:
skinbox.addskin 1055319033 349762871 915408809

The skin id has to be 9/10-Digits.

And Enjoy all the skins you could ever want on the Valhalla Server for free.
