Sublimation ready neoprene pouches for tumblers. *Tumbler NOT included! Hook and loop closure allows easy adjusting to fit just about any tumbler, not just the 40oz tumblers! Zipper closure. All options (both white and colored) are sublimation ready. White pouch is double sided for sublimation. ***Pressing Instructions*** Make sure to tape the transfer well or use adhesive spray (I recommend tape). Place transfer on top of the substrate with the image design facing down. Place between blowout paper. Press at 400 degrees for 60 seconds with medium light pressure. *Make sure the plastic clip on the strap is hanging off the heat press or it will melt!!! I also recommend putting the hook and loop strap behind the pouch when pressing (or protect from the heat very well).
