crazyquilter, there is a detailed description of all Machin security features including the oval slits at this website...www.adminware.ca/machin/m_tech.htm#Security. They are meant to prohibit the removal of the stamp from paper for re-use. I have successfully removed these stamps, however, using Pure Citrus and careful use of a straight-edge on the back of the stamp to remove the adhesive.

No longer in denial! I collect all of it...the whole world! Just printing and mounting as I go! Call me crazy.
Only noticed them on the self-adhesive ones. Have to be careful peeling them off the sheet for affixing to the envelope...
I am a letter writer, snailmail addict. I send therefore I receive. I also manage a letter writing/correspondence forum called A World of Snail Mail and have a blog (link is in my profile). I sometimes post pictures on Instagram (username morgaine_does_snail_mail) Stamp themes - science, nature, postal history, maps, nice stamps.
