Instructions for use

Upon opening the box, familiarize yourself with the schedule displayed on the lid. You will smell train four scents per day, two scents in the morning and two scents in the evening. This will repeat five days a week for eight consecutive weeks.

Step 1: Always begin by cleaning your hands. This ensures that you avoid any potential irritation or infection.
