Ruby Love Period underwear (one level) in every brand's language
By Ruby Love's own published claim, its Period underwear (one level) tier holds 12.5 mL Data quality grade B, converted from tampon counts. Tier names don't transfer between brands - millilitres do. Here is the smallest tier in each other brand whose claimed capacity covers it.
The source claim
Ruby Love Period underwear (one level): 2.5 tampons
The covering tier in each brand
“Covering” means the smallest tier whose claimed maximum meets the middle of Ruby Love Period underwear (one level)'s range (12.5 mL). Grades: A = brand publishes mL, B = converted from counts at a stated basis, C = conflicting or unconfirmed.

All figures are the brands' own maximum-capacity claims, normalized to millilitres - claims made comparable are still claims, not lab measurements (the only blood-component study, BMJ Sexual & Reproductive Health 2023, measured far lower effective capacity than marketing figures). Sources, conversion rules, and verification dates live in the methodology.
