An insertion device 10 for inserting material 13 into a body cavity is provided. An elongate, tubular holder 12, shaped for insertion into the body cavity, is adapted to hold the material to be inserted. The holder 12 has a material expulsion end portion 14 and a plunger 20, which is telescopically and slidably mounted in the holder, which is adapted to expel the material from the holder when pushed manually into the holder. The holder, and preferably the plunger as well, comprises an outer paper layer 28 and a polymer layer 30, adhered to the paper layer on its outer surface, the layer having adequate water resistance to maintain its integrity during insertion into the body cavity.
