Safety
Unlike plastic teethers that can contain liquids or other harsh chemicals,
untreated wood or water based, oil based or beeswax finished woods are so
much safer and completely natural. Which is also why wood is commonly
used for cooking, i.e chopping boards, spoons etc... It is also far more durable
than plastics.
There are certain woods that are used for teethers, all of which are hard
woods that do not splinter.. The popper fastening also acts as a safety
feature, even though very strong and takes a lot for it to un-popper, if it is
pulled really hard it will just un-popper rather than break and also prevent
risk of strangulation!
