 So the thing no one tells you about periods is that your flow changes every day and so should your tampon size. Tampax has five absorbencies to match your changing flow. If it's uncomfortable to remove, go down a size. If it leaks, go up a size. And only Tampax has a leak guard braid to help give you up to 100% leak and odor-free protection. All-day comfort and protection for up to eight hours for under $5 a month. Based on average U.S. consumer usage at manufacturer's suggested price. However, pricing is at the sole discretion of the retailer. Excludes account pack.
