Help with making scalable textures for vital bars

I’m having issues scaling my vitalbar textures for the actual vitalbar. Every time I bring the texture over from GiMP, it stretches out, becoming blurry and bad-looking. I need help with figuring out what I did wrong with making a scalable texture.

Pictures of the texture in GiMP (initial texture) and in the Unity editor (stretched out texture) are available in the .zip file below.

You got to deal with GUIStyle.border. Basically you have to include the part of the image that you don’t want to be stretched to [left or right] and [top or bottom] part of your RectOffset. So, try to set top and left to width and height of your image for a start, and right and bottom to 0.
