We print items on demand so the products you receive from us are hot off the press! For this reason you might notice a new shirt or hoodie has a vinegar-like smell or an off-white residue. That’s normal and it’s from a fixation agent applied during the printing process. This is used for direct-to-garment prints and helps the ink bond with the fabric because without it the ink would flake off the garment. Neither the residue nor the smell are permanent and both should go away after one wash.
