Pro Formula Whitening Gel Pens – 1,9 ml – 2 Stück

Took it on a weekend trip and the 1.9mL per pen was plenty for morning and night touch-ups. The gel dries fast enough that I wasn’t wiping it off my teeth every five minutes, which is my usual complaint. Two pens in the pack means I’ve got a backup for when I inevitably lose the first one in my bag.

The pen applicator is super precise, so I can target just the stained spots without making a mess. Two pens in the pack means I keep one in my bag and one at my desk, and the 1.9mL size has lasted me weeks of daily touch-ups.

The 1.9mL gel amount is just right for a couple weeks of nightly touch-ups, and the pen applicator makes it easy to target the front teeth without making a mess. I've been using it after coffee and already see a subtle difference on my lower incisors.
