Twice as nice. The Saalt Soft Duo Pack includes both sizes of our ultra-soft silicone cups making it perfect if your flow or cervix height varies during your period, and you experience bladder sensitivity, cramping or discomfort with firmer cups. Our premium cups are made in the USA from 100% medical grade silicone with a velvety soft finish. The cup is worn internally like a tampon, but collects rather than absorbs your period.
