Invisalign™ Whitening Pen Twin Pack

Don’t order items directly from Invisalign. It is very difficult to return items. I’ve been trying to return this item for about a week and a half. I am following the instructions on their website which is to email them with the order details and the order number and I have not heard back much better to just buy from Amazon so if you need to return something you can.

It's effective and easy to use.

I ordered two ( 2pk) of the Invisalign whitening pens. One pkg only contained 1 pen. It was dried out. The other package had 2 dried out pens so I am very disappointed and will be emailing about it.
