Vivid Temporary Sleeve Tattoos Sleeve tattoos are a thing of wonder and a testament to the artists craft. Though they also tend to be expensive, labor-intensive, time intensive, and arguably a little uncomfortable to have applied. Not to mention they are perhaps a little too permanent for something as simple as a Halloween costume, cosplay event or costume party. Stepping up to answer this call are these temporary sleeve tattoos. They have vivid artistry and colors that are eye catching, and are also easy to work into a variety of cosplay themes.
