like it was terrible [SEP] i do not know what it is with this cap but it leaves stains on your bed when i first wore it to sleep i woke up the following morning to see horrid blue stains on my pillowcase like it was terrible all over the pillow case i hand washed my pillow case and some of the marks are permanent i mistakenly left the cap on my bed this afternoon before heading out i came back to see the same monstrous bluish black stains on my bedsheet i am so frustrated with this to think i trusted the reviews before buying it i feel like i wasted my money oh well
