What is Orbee-Tuff? (FAQ explained by Planet Dog)
"Orbee-tuff is a plastic we developed and has no latex in it. It’s a
thermo plastic elastomer (TPE) to be precise, but instead of using any
of the chemical softeners (such as Phthalates or BPAs) used in vinyl and
other plastics we use White Olefinic oil to soften, which is very much
like Baby oil and completely safe. We also add a small amount of
essential Peppermint oil. Our toys have been tested and shown to be
non-toxic many times since Orbee-tuff was introduced 10 years ago."
