White Republic formula has definitely helped me whiten. However, I am not sure if it's also because I stopped my coffee addiction (hardest resolution for 2023!!)
Good quality whitening gel. My teeth are very yellowish so I decided on using the extra strength formula. No regrets :)
Effective but I don't feel a difference Vs the normal whiteing pens
I ordered this as I ran out of normal gel pens and wanted to try the stronger formula. I recommend as my teeth are whiter than ever!! 🦷😛
Similar pen than the normal pens but stronger formula. Good packaging and fast shipping. 🤩 Thank you White Republic for this amazing gel formula
Amazing results with this extra formula!! I got 3 shades whiter after 7 days. I will push for more days and let you know!!
I'm not so sure about how more powerful than the original gel pens this one is but I know one thing for sure: EFFECTIVE ! I love the results :)
Extra gel pen is the best one for me as I had very yellowish teeth from the start
In love with White Republic 😍 I'm still in the process of using it, but the results so far have been mind blowing!!
Good packaging, pen is well protected and packed
This comes with only 1 gel pen. Stronger than original gel pen but not much sensitivity. Good pen

Got this along my wireless Kit - I like the strong formula as my teeth are soo yellowish to start! But now it is improved by a lot. I received positive comments from my mom yesterday haha
My first treatment (with the kit set) was around January time. I thought it was time for a refreshment and maintain whiter teeth
It does the job. Delivery properly packed.
This is my favorite pen. If you ever want the pearly white smile this is the best product !🌟
I added this add-on to my wireless kit. I'll keep it for maintenance sessions - let's see how it goes -->🦷

I tried it at my cousins and was delighted with the product. My teeth was a bit whiter just after one session for fun. Now they're whiter than they have been for years. Great gel White Republic 🥰
Fast delivery. I will try it tonight for the firs time..
I noticed good results very quick. Looking forward to seeing how white my teeth can get.
I love the White Republic pens so much 🤩 They work fabulous, and the results are quite fast too!!

The results are ok but I preferred the normal pens from my wireless kit. I feel like the taste of the extra strength gel is different! I don't like it
I apply it while watching Netflix ! Top formula that actually does work on my teeth

Extra pen for extra whitening! I don't know how much stronger it is compared to the original pen but it does the job too..
Just reordered more gel pens and 1 extra last week. Arrived smoothly. As I expected, good quality and good packaging.
Better than anything I have tried so far to whiten my teeth
Good gel, working. It seems to be more powerful than the other gel! Thank you White Republic for creating this extra strength formula
I love this product I use it while I study so I really do not have to think about it much. It does all the work for you
Got this to touch up my smile right before the christmas partieeeess!!🎄
