Made of medical-grade silicone, it appears to be a Chinese product made to Japanese standards. It's similar to the Super Jennie, but slightly softer and easier to expand, providing a good seal with almost no foreign body sensation. The stem is thick and easy to use. I've tried various cups like the Meluna and the EvaCup, but personally, this is the most comfortable. This is the price for one size S. If you want to purchase multiple, please let me know in advance. I also have a foldable cleaning cup, which I will include for free if you need one. L size in pink and purple are also available. If you want to combine shipping, I can offer a discount on the shipping cost, so please let me know.
