Beware. These are not silicone. These may be toxic.
on August 18, 2017
The information about this product from Amazon is terribly inaccurate. See image attached from the Amazon website, which shows that these stoppers are silicone. However, as the packaging shows (see photo attached), they are made of a synthetic rubber (styrene-butadiene rubber, SBR), a material that may be toxic. (I would add links to research, but Amazon does not allow outside links in reviews. Search for "styrene-butadiene rubber toxicity" to find the information.) Big fail for both Amazon and Rabbit, and a real waste of my time. Beware. I'll be returning these NOW!!!!! And I will no longer trust Amazon descriptions or Rabbit products.
