Before you decide to buy this, keep in mind this requires you to have the mod Optifine installed to your client.
You can download Optifine here, and can install it by doing the following:
1) Locate your minecraft.jar file. On Windows, it's in %APPDATA%/.minecraft/bin
2) Create a backup of minecraft.jar
3) Open minecraft.jar in an archive editor (WinRar/7-Zip/etc)
4) Delete the META-INF folder.
5) Copy (drag and drop) the .class files from the downloaded zip file into the jar file, replacing previous files.
6) Run Minecraft and test!
Once you have Optifine enabled, then you can see the cape and decide if you want to buy it! Optifine is a minecraft visual enhancer and I recommend it fully.
The Optifine cape is a cape obtained by donating $10 or more USD to the owner and creator of Optifine. I realize that not everyone can just open a paypal up and donate, however, I can. I am going to be selling two (2) optifine capes. To those who may ask, yes this acts completely like any other cape. However, can only be seen with people who have optifine.
Each cape will cost 50,000 MTC (for the reason that I am paying real life money for these, and to keep them rare)
Pictures of the cape can be found below:
Thanks and REMEMBER, YOU NEED OPTIFINE TO VIEW THESE, DON'T BOTHER BUYING IT IF YOU DON'T WANT THE MOD.
EDIT: All capes are sold out! Sorry if you didn't get one, I may reopen again in the future.
