Boka is an oral care product subscription. You can get toothbrushes, electric toothbrush heads, toothpaste, floss and/or mouthwash.
This wasn’t a subscription shipment, though. Once you subscribe you are given a referral link and if anyone signs up using your referral link you get free products.
If you’d like to sign up for Boka you can do so here: http://fbuy.me/d4XS5
Be sure to pass on your own referral link to your friends once you sign up!
