i just got 30 amps of these omnas never used them before .... i been readin up on it but i figure i'd post the pics if anyone can authenticate them .... i never got them in a box they were delivered in a doggy bagwhat u gonna do ... anyways the number is 030204 ex 02.2007 they have a letter Y on them and from what i can tell a small incesion right under the white dot around the neck of the ampule no wider then 2 mm (sort of a pre-cut for easy cutting) they have a somewhat strong but sweet like smell.... (actually reminds me of a hospitals back in europe from young years).... when u crack them open.
