If your pen's display is flashing upon arrival it probably also doesn't have a plastic tab in place to protect the battery.

Don't worry about this!

It means that your unit was picked off the assembly line by our quality control team for a routine quality test. Your unit has been hand tested - and passed the stringent test - to ensure that the cap is of the highest quality that we promise our customers.

This won't affect the battery life of your pen at all and you will have over one year of use from your Timesulin cap before having to replace it, as standard.

Aren't you lucky!
