3 Sperm Egg Pen from Fertility Clinic.

Two say CCRM Fertility

One says Advanced Fertility Care

All three you twist the bottom to make the pen part come out. All three work.

The Advanced Fertility Care pen has more wear from being stored in a drawer. I’m not sure how long the ink will last in that case be because it is the oldest and was used. The CCRM pens have not been used and are newer.
