Reusable menstrual cups or disposable

Reusable Menstrual Cups

For a review of my first time experience with a reusable menstrual cup please read

There are many different brands of reusable menstrual cups. The one that most people know is the Diva cup. This is the one that my sister uses because it was easy to pick it up at the drug store. I am currently using the Eva cup which is made in the USA in California and cost about $21 at least when I bought it and had free shipping at the time. I am thinking of purchasing the Lily cup which has a different design than most reusable cups on the market and looks like it would be good for a heavy flow and high cervix.

Some popular brands of reusable menstrual cups are:

Lilly Cup


Lily Cup - Menstruation Cup Sizes

Lily Cup Compact - Menstruation Cup Sizes


Diva Cup

Eva Cup

Femmy Cup




Each brand of reusable menstrual cup is slightly different. The ones I attached pictures to have a more unique design. Most menstrual cups range in price from $21-$40 and almost all cups come in two different sizes. The #1 size or A size depending on the brand is normally the smaller size for women/teens under 30 and who have not had children but these are also good for lighter flows. The #2 or B size is recommend for women who are over 30, have had children, have a heavier flow or a weaker pelvic flow. That is part of the reason I am thinking of getting the Lily Cup since it has a capacity of 32 ml for the #2 size and the #1 size has a capacity of 28 ml. The lily cup compact on the other hand has a capacity of 18 ml for size 1 and 23 ml for size 2, these I believe would be good for young girls just starting their period or very light flows. The lily cup compact seems to be the smallest cup on the market.

The brand I currently have, the EVA cup has a capacity of 30 ml in the #1 size and 37 ml in the #2 size.

They may have changed the size of their cup since I bought my size 1 since my EVA cup is only 25 ml capacity which is why I am considering getting a bigger capacity cup like the Lily cup or getting the size 2 EVA cup since I have a heavy flow for at least 2-3 day and can not go 12 hours without emptying my current cup.

The largest capacity cup I could find is the Super Jennie, the #1 size capacity is 32 ml and the #2 is 41 ml and at $29.95 this was a great purchase for me. I bought the size 2 and was skeptical at first when i compared it to the size 1 Eva cup. It was way bigger but worked great and the larger capacity is wonderful. I highly recommend for those with a heavy flow.


Disposable Menstrual Cups

There are a few options in the disposable menstrual cup area if the reusable option is not your cup of choice. Although I do love that the reusable menstrual cups can last for up to 10 years if properly taken care of, sometime the disposable menstrual cups are useful.


Instead Soft Cups ( now owed by the Flex Company)

There are two types of disposable Instead Soft cups. These can be bought drugstores like Walgreen’s or Rite-aid or CVS. The one in the pink and white box are to be used once for up to 12 hours and then disposed of. There is also a version of the Instead Soft cup that is reusable for one full cycle. I have not seen this one in store but can be bought online. I found it on amazon but it does not seem to be easily available anymore. It comes in a green and white box in case you ever see it.


There is also the Flex cup which bought Instead Soft Cups. From what I can tell and reviews I have seen this seems to be the same as the disposable soft cup but in a different color and more expensive. When it was first announced that the flex was going to be released I though it was going to be this cook new menstrual product but it looks just like the soft cup. According to the Flex company website there is a small difference:

“How is FLEX different from Softcup®?

The Flex Company makes both Softcup & FLEX, which are both menstrual discs. The key difference is in the materials and service FLEX provides customers. FLEX is made with newer technology & materials. FLEX uses your body heat to warm up to form your natural shape, creating a leak-free seal.

FLEX customers have premium access to subscriptions with free shipping, phone, chat and text support.

We’ve also designed our packaging to make for more convenient carrying and disposal.”

They offer a free 1 month trial and then it is $20 per month after that and they ship a new monthly supply of 8 flex disk each month for that $20 monthly fee.

The disposable Soft Cups for a 12 pack is about $12 at the drugstore which I feel is a much better deal even with the claim that the Flex disk has newer technology and materials.

I have a box of Instead Soft Cups that I use occasionally with my EVA Cup. My personal review of the soft cup is that it is good for lighter days. I will use one on the second to last day or last day of my period. It is comfortable, it is actually easier to put in and take out but I feel it is slightly messier and leaks a little when using the bathroom when not ready to be removed just yet. My box of 12 has actually lasted me over a year which is also why I don’t see the need to pay $20 a month for the Flex subscription.

Comparison between a reusable menstrual cup and a disposable menstrual cup

From the Flex Company FAQ

FLEX is a single use device and was created to be discarded after each use as a more convenient alternative. Menstrual cups are meant to be rinsed and reused for every cycle.

  • Menstrual discs are soft and fully collapsable with a thin membrane center and flexible outer rim; menstrual cups are firm and bell-shaped with a stem
  • Menstrual discs are worn in the vaginal fornix, at the base of the cervix; menstrual cups are worn in the vaginal canal
  • Menstrual discs can be worn during sexual intercourse; menstrual cups must be removed before vaginal sexual intercourse
  • Menstrual discs have one method of insertion and removal; menstrual cups may be folded and inserted in a variety of ways
  • Menstrual discs generally have a similar size and shape; menstrual cups come in a variety of shapes and sizes
  • Menstrual discs have not been linked to TSS; though rare, menstrual cups have been linked to TSS
  • FLEX is made of medical grade polymers that get softer inside of your body; menstrual cups maintain their hardness inside of your body
  • FLEX is hypoallergenic, made without silicone or natural rubber latex; most menstrual cups are made of either natural rubber latex or silicone
 My personal observations are that the soft cup/ flex disk has an easier learning curve than a reusable cup but the disposable cups have a smaller capacity then reusable cups. I find both to be equally comfortable and depending on your needs one might be a better option than the other.
