Timeline History NNSL
Mr J.Koopman founded the Noord Nederlansche Stempel- en Leermiddelenfabriek (NNSL) in Groningen, the North of the Netherlands. He started with stamps. After selling a set of rewarding stamps to a teacher, the development of stamps and other educational products started.
From the 60s, the Stempelfabriek expanded every year by producing educational stamps and other educational products. Mr. Koopman started visiting international teaching aid fairs and the first orders from Belgium, Germany and the USA were a fact.
Jegro and the Noord Nederlandsche Stempelfabriek joined forces to be able to offer a full range of additional educational materials. The trade name became Stempelfabriek & Jegro. In addition to the standard assortment they started producing custom made products.
Stempelfabriek was taken over by the Heutink Group. Jegro is now 1 of the 4 brands of Heutink International. Stempelfabriek products are covered by either the Educo or Jegro brand, depending on their target group age. NNSL still produces these products in its factory in Groningen.
