Menstrual Cups

Rainbow Cup / Monzcare R-cup


Couldn’t find an official site for these, just being sold online at places like ebay and amazon.  So details are a bit sketchy.

This cup is also being sold as a “Monzcare R-cup” and “Monzcup”.  They are registered with the FDA under these names [Link].

Country of origin: China
Composition: Silicone
Sizes:  “1″ (small), “2″ (large)
Dimensions:  Size 1 = 40mm diameter, Total length 70mm, stem length 20mm.  Size 2 = 45mm diameter,  Total length 70mm, stem length 15mm.
Capacity: Size 1 = 15.5ml (to holes?)  20ml (to rim).    Size 2 = 26mls (to rim?)
Stem: Hollow tube or Solid?
Measuring Lines:  No
Cost (RRP): Unknown RRP – available from around $10US
Been around since: 2014?
Other Details:  Available in blue, green, purple and orange.  I don’t like that their advertising claims “The Rainbow’s Menstrual Cup is the original silicone menstrual cup designed by women to be a convenient, safe and eco-friendly alternative to tampons and sanitary pads. ”  Since it isn’t the original silicone cup…. Mooncup UK was the first silicone cup in 2000.     Some people have complained that these cups have a very strong “plastic” or chemical smell.

  1. I have a large Rainbow and didn’t notice any smell at all. I love that it’s super soft and on the long side for my high cervix, and I find the slightly firmer rim and the grip rings helpful. I wish it were even a bit longer in the stem for my highest cervix days but overall, I’m a big fan. It’s just as well made as any other, much more pricey cup I’ve used. Unfortunately I don’t see them on Amazon anymore, but they’re still available on Ebay.

  2. That’s the problem with cups like this that have no website, it’s just a case of checking ebay/Amazon regularly to see what’s available.
