Hi Harry,
Very interesting your item
regarding Anshin.
I think you are right: it is not a
Japanese tampon.
In the U.K. Robinson made them
(also the makers of Nikini). They
were called Cameo tampons. See
an ad in the Woman's Mirror
(May 22, 1965) [here].
The same tampon was sold in the
Netherlands in 1972 by Unicura; see
the scans of the instructions (on
one sheet 107 mm x 83 mm; if folded,
it has 4 pages). To market it, you
could win in the "Ortex Goudfestijn"
(Ortex Goldfestival) gold objects.
See some pages of the folder (it is
threefolded, 2 x 3 pages, I scanned
2x2 pages) [see
all below].
BTW: Unicura was the same company
that sold Tassaway
menstrual cup in 1972/1973 [in
Europe; see an ad].
But if the ads are an indication,
after 1972 Ortex disappeared
from the market or had a very small
part of it.
NB: I think the tampons are not
made in Holland; the instructions on
it are written in English!!
So I think that Robinson tried to
conquer the market in the U.K. but
didn't succeed (in the long term).
Later, it exported it to
Holland/Belgium and Japan and maybe
other countries as well.
I send you the scans as raw
material to you.
