These do not come with shrink wrap. These can be wrapped in tape and with a heat press or placed in a convection oven.
For a convection oven, remove all plastic pieces, measure the metal barrel, pull it tight, and tape it to the top, middle, and bottom.
Press at 400 degrees, for 2 minutes, rotate 1/3, press another 2 minutes, rotate 1/3, and press another 2 minutes. For a convection oven, bake 400 degrees for 2 1/2 minutes, turn halfway and press another 2 1/2 minutes. Keep in mind, that all ovens and presses vary and your temperature and cook/press time may be different.
