We're sorry for any confusion, Ali. We can assure you that our Whitestrips go through strict quality checks to ensure that they reach you in the best possible condition. This product is intended to arrive in a cardboard box, as it ships in its own container. We'd also be happy to share the instructions with you. For best results, we suggest you use your Professional Effects strips first. Use 1 every day, or as close to every day as you can, until the entire set of Professional Effects strips is complete. Professional Effects strips should be worn for 45 minutes. After you have finished using your Professional Effects kit, you can use 1 Supreme Bright Boost strip each month thereafter, to maintain your white smile. Supreme Bright boost strips are worn for 1 hour. We hope this is helpful, and please give us a call at (800) 395-8423 if you'd like any further assistance.

We have had many clinical studies have shown that Whitestrips are effective. However, if you have stubborn stains you may need to use a second box of Whitestrips to achieve the results you want. We'd like to make sure your smile is left bright and white, so when you have a minute can you please reach out to us at (800) 395-8423?
