Spec and price sources Model, match basis, check date
- Original name
- Kobayashi Menstrual Stain Removal & Antibacterial Laundry Detergent for Women's Underwear 120ml
- Model
- 120ml bottle; JAN 4987072066447; source category: intimate care
- Spec
- Japan ranking title: 120ml; a separate source category field says 100g per bottle; JAN 4987072066447. Taiwan product page: 120ml. Paired as one 120ml bottle using the product name and matching JAN on the Japan and US product pages.
- Same-item basis
- The brand (Kobayashi Pharmaceutical), purpose (laundry detergent for women's period underwear), and volume (120ml) match exactly. Root re-verification: momo product page re-check: Kobayashi Pharmaceutical Period Laundry Detergent 120ml, NT$199. The Japan listing's product name states 120ml (the source's category field separately states 100g; the 120ml in the product name governs), so both sides are 120ml.
