Brand name Chemboys, purchased through Amazon (4/22/22), a company out of Boston, MA. No expiration date. Price $46.73. Return window closed 6/4/22. Opened on 11/14/22. Foil seal good, no signs of any tampering. Very noticeable smell of what reminds me of alcohol, or nail polish remover, or paint thinner. Not seeking compensation for I am a fool for not immediately returning within the window time frame for no expiration date on the jug. Buyer Beware. Thank you.
