There might be at least one odd exception - the lenticular lens Montreal Canadiens "stamps" were printed in New Zealand, and others I've seen of that type were unsoakable. I got a munched up French soccer or rugby lenticular stamp (can't remember which) also produced in New Zealand, so I tried soaking it - nothing happened, the stamp didn't come off the paper, but the lenticular lens didn't come off the stamp either.
