The classic Amsterdam. Named after the most open city in the world, it is a proven performer! We only sell genuine brands, and this is the newest packaging, in a shrink label to avoid making it easy to fake! If you find Amsterdam in a small bottle elsewhere, and it does not have this new shrink label, then you have found a copy-cat, and you DON'T want that!!! Always remember that poppers are for cleaning purposes only. NEVER for personal use/abuse.
