In the 1990’s , Thomas Dam company licensed rights to it’s trolls to EFS Marketing Associates. EFS sold trolls under the Norfin brand name. Norfin trolls are a high quality troll with great features and a wide variety of sizes and outfits. These are really Dam trolls since it was a licensing agreement not a manufacturing agreement. They look different from the really old Dam trolls but they are marked Dam on their bodies.
For simplicity and ease of identifying trolls, I have included the Norfin Dam trolls under the Dam trolls category. Most people don’t care that it is a Norfin troll. If I know that it is a Norfin Dam troll, I will mention it in the description of the troll.
