Thank you for your interest in Walltat wall decals! The decal comes assembled as is, however each part is separate. So if you wanted to install just the eyelashes and eyebrows, you could cut off the nose and mouth easily and install just the eyes. However, they do come assembled as pictured.

how big are the eyebrows?

Just the eyebrows by themselves are 11in W x 5in H for the one on the left and 14in W x 5.6in H for the one on the right (at the angle they are shown in the picture). Let us know if you would like any other sizing!
