When the colourful knights tumble out through the castle's secret doors, the dragon spectacle is in full swing. The turbulent, reissued classic game Rumpelritter & Das große Drachenspektakel from HABA brings real knightly fun for the whole family from 4 or 5 years of age.The contents of the game box include several locking rings for the secret doors - the transparent O-Ringe aus Silikon are manufactured by KREMER.. The medium hardness of 70 Shore offers a good compromise between flexibility and strength, so that the rings fulfil their purpose reliably and flexibly on the one hand and are hard-wearing for long-term use on the other.

Because the silicone rings from KREMER are used in the Rumpelritter in a children's toy, they have been tested in accordance with toy standard EN71-3 category III. This ensures that children are protected from harmful substances when playing.

The Anwendungsbereiche für O-Ringe are enormous and there is a wide range of variants. Approval for use in contact with food (FDA, BfR) is also possible – sprechen Sie uns gerne an!
