When I remove the strips after 30 minutes, all the gel remains stuck to my teeth. Following use, there are white spots visible on my teeth. However, this sensitivity disappears by the next day.

This item arrived in good condition, and this is not the first time I've purchased it. It makes your teeth whiter.

This is my second time using it. It's very good, but to maintain the outcome, avoid consuming any beverages or foods that could cause staining.
