Intimina (Lily Cup) vs Sileu Menstrual Cup: What Really Changes?

“Is a Lily Cup really worth double what other cups with the same certification cost?” This question, which reaches our support inbox every week, sums up what people wonder when comparing the Intimina menstrual cup with the Sileu menstrual cup. And the short answer is uncomfortable for marketing: what actually changes isn’t safety or material, it’s price, the models available, and what you get for your money. Intimina is an international brand with good design and shelf presence in major retailers; Sileu is a Spanish direct-to-consumer brand with seven cup models. Both make safe cups that work. Let’s compare them with verifiable data and no tricks, just like we did with Enna vs Sileu.

The Intimina prices cited here are the ones published on their official website in August 2026 (€26.95 for the Lily Cup One, €30.95 for the original Lily Cup, and €32.95 for the Lily Cup Compact, VAT included), though the brand frequently runs discounts: double-check before deciding. The Sileu prices are our store’s, no fine print.

Price: the clearest difference

A Lily Cup costs around €27-33 depending on the model. For less than Intimina’s cheapest option, at Sileu you get a Sileu Rose (€19.99) with change left over for sterilizing tablets. And for the price of a Lily Cup Compact, you get the full Sileu Travel Pack: cup, foldable sterilizer and pouch for €29.99.

Why this difference? It’s not material or quality: it’s the channel. Intimina sells through international distributors, and each middleman adds their margin. Sileu sells direct from the factory, with no tolls along the way. Either cup pays for itself within a few months compared to tampons and pads, but the upfront cost doesn’t have to top €20.

And here’s an honest thought: the disposables industry bills you every month, cycle after cycle, for decades. A €15-20 cup that lasts for years has nobody advertising it on TV, which is why people who switch to a cup — whatever the brand — usually end up wondering why nobody showed them sooner.

Models: 3 foldable cups vs. 7 models matched to every body

Intimina’s approach is genuinely original, and credit where it’s due: the original Lily Cup rolls up as thin as a tampon, the Lily Cup One targets beginners with a removal ring, and the Lily Cup Compact folds into a pocket-sized case. Their bet is on format: cups that take up little space.

Sileu’s bet is different: instead of folding the cup down, we adapt the cup to the body. There are seven models with different shapes, lengths and firmness levels: Classic (balanced), Soft (sensitive bladder or vagina), Sport (strong pelvic floor), Rose (beginner-friendly, rose-shaped, with a Spanish design story behind it), Tulip and Bell (low cervix), and Divine (maximum softness). Our experience after years of advising customers is clear: the number one reason people give up on the cup isn’t that it doesn’t fold — it’s wearing a model that doesn’t fit their anatomy.

And within the range, customization goes right down to the detail. Only the Sileu Rose comes in 18 combinations: 3 sizes × 3 firmness levels × 2 colors. Choose exactly the cup your body needs:

Size	Soft firmness	Standard firmness	Sport firmness
XS (teenagers)	Red · White	Red · White	Red · White
S (typical starting size)	Red · White	Red · White	Red · White
L (postpartum / heavy flow)	Red · White	Red · White	Red · White

If you were looking for a specific Lily Cup, here’s the honest equivalent within our range:

• Drawn to the Lily Cup One (beginners)? Its closest match is the Sileu Rose: designed as a first cup, with clear guides for folding it and inserting it.
• Drawn to the Lily Cup Compact (foldable, discreet)? The Compact appeals to people with limited vaginal space or a low cervix. Our alternative isn’t a foldable cup, but a model that’s short by design: the Sileu Tulip or Bell, made for a low cervix. And for discretion in your bag, the SileuCase (€3.99) serves the same purpose as Intimina’s little case.
• Drawn to the original Lily Cup? It’s an elongated cup for a mid-to-high cervix; at Sileu, the Classic or Soft cover that use case with two real sizes.

Materials and certifications: no shortcuts anywhere

Intimina makes its cups from medical-grade silicone and rightly touts its health registrations. At Sileu we use German silicone from the brand Wacker, certified to the ISO 10993 biocompatibility standard (surgical-medical grade), the same family of standards required of medical devices. You can read our breakdown of menstrual cup quality certifications and what medical-grade silicone actually means.

On material safety, this matchup ends in a tie, and that’s how it should be: no serious brand cuts corners with your health. Our standing advice: be wary of any cup without biocompatibility certification, no matter the price.

Size and anatomy: what no brand can choose for you

Intimina simplifies things with A/B sizes based on childbirth and flow. Sileu uses S and L, and adds the variable that really matters: your cervix height. Before buying any cup, from any brand, spend five minutes finding your cervix: it’s the difference between getting it right the first time or the cup ending up in a drawer. If you’re still torn between sizes, the Starter Pack S+L (€21.99) includes both so you can try them and keep the one that fits — something no Lily Cup offers.

Capacity and overnight use: read the fine print

A detail that often gets overlooked when comparing the Intimina menstrual cup with other brands: the Lily Cup Compact, being foldable, has less capacity than a conventional cup of its size. If your flow is heavy, a small foldable cup can force you to empty it more often — the exact opposite of what you want from a cup. Across the Sileu range, the L size of any model offers maximum capacity, and every cup can be worn up to 12 hours straight, including overnight, always following toxic shock syndrome safety guidelines. We’re not the only ones saying it: the systematic review published in The Lancet Public Health (43 studies, over 3,300 participants) concluded that the menstrual cup is safe and its leakage rates are equal to or lower than tampons and pads. Knowing your menstrual flow volume will help you decide on size using data instead of guesswork.

Where to buy and what happens after you buy

Intimina sells through its international website and marketplaces; support is usually in English or through generic forms. Sileu sells direct from the factory at sileu.com with shipping from Spain in 24-72h, support, and our own content to guide you: from an FAQ to guides on cleaning and sterilizing your cup or solving issues like the cup shifting or slipping out. When your cup raises a question at 11pm, this matters more than it seems.

So, Intimina or Sileu?

Choose Intimina if the foldable or rollable format is your absolute priority, paying around €30 per cup works for you, and you prefer an international brand with Scandinavian-style design.

Choose Sileu if you want certified silicone at the best price (from €14.99), a model chosen for your anatomy out of seven options, two real sizes with the option to try both, and close support. If it’s your first cup, start with our guide to choosing your first menstrual cup.
