Thanks to the tremendous amount of positive feedback and advice I received, I have decided to buy the small si-bell. I have found a site (https://www.coppetta-mestruale.it/en/sibell.php) that sells the pink cup for 23 euros (31.5 USD since I live in the US). That is still pretty expensive, and I don't want my (skeptical) mom to decide not to buy this cup due to the price. I have tried going on the si-line site (si-line.eu), but for some reason, it is closed, and in femininewear.co.uk, si-bell is out of stock. Does anyone know why? And does anyone have one they are willing to sell?
