These air-activated pads warm to 130 F for six to eight hours. Avoid use while sleeping, and seal half-used patches in an airtight bag for later. - STICKS TO UNDERWEAR, SPARES SKIN: No skin reactions or painful peeling. These patches transfer warmth through clothing rather than sitting on skin. Paste over underwear and air out hourly to avoid heat buildup. - IDEAL SIZE FOR DISCREET USAGE: Each patch is 2.75x3.5 inches — small, smooth, and thin enough to go unnoticed under an outfit while covering the area that matters. - 1x10 PATCHES PER PACK: One pack lasts one to three cycles depending on severity and frequency. We recommend using two at once — one over the lower abdomen, one over the lower back. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0B836F1YT | | Additional Features | Disposable | | Age Range (Description) | Adult | | Age Range Description | Adult | | Best Sellers Rank | #47,772 in Health & Household ( See Top 100 in Health & Household ) #63 in Adhesive Heat Patches | | Brand | SunnyBay | | Brand Name | SunnyBay | | Color | White | | Container Type | Pack | | Customer Reviews | 4.3 out of 5 stars 1,999 Reviews | | Item Form | patch, stick | | Manufacturer | BioMed DB Design, LLC | | Manufacturer Part Number | 2023 | | Material | Air-activated, lightweight, flexible material | | Material Type | Air-activated, lightweight, flexible material | | Model Name | Heat Patch for Menstrual Cramps | | Model Number | 2023 | | Number of Items | 10 | | Number of Packs | 1 | | Product Style | Casual | | Size | Small | | Special Feature | Disposable | | UPC | 850008067518 | | Unit Count | 10 Count | ## Product Details - **Age Range (Description):** Adult - **Brand:** SunnyBay - **Number of Items:** 10 - **Special Feature:** Disposable - **Unit Count:** 10 Count ## Images ![SunnyBay Heat Patches for Menstrual Cramp, 2.75x3.5 inch, 10 Count - Image 1](https://m.media-amazon.com/images/I/71TuStpWWaL.jpg) ![SunnyBay Heat Patches for Menstrual Cramp, 2.75x3.5 inch, 10 Count - Image 2](https://m.media-amazon.com/images/I/71AaBiT883L.jpg) ![SunnyBay Heat Patches for Menstrual Cramp, 2.75x3.5 inch, 10 Count - Image 3](https://m.media-amazon.com/images/I/814WhmEU1bL.jpg) ![SunnyBay Heat Patches for Menstrual Cramp, 2.75x3.5 inch, 10 Count - Image 4](https://m.media-amazon.com/images/I/8122N1NGGCL.jpg) ![SunnyBay Heat Patches for Menstrual Cramp, 2.75x3.5 inch, 10 Count - Image 5](https://m.media-amazon.com/images/I/71Onkj0opdL.jpg) ## Available Options This product comes in different **Size, Unit Count** options. ## Frequently Bought Together - SunnyBay Heat Patches for Menstrual Cramp, Air-Activated Adhesive Heat Pads for Period, 130 F Warmth up to 8 Hours, Stick to Clothing Not Skin, 2.75 x3.5 inches, 10-Count - (5 Patches) CrampCareH PMS/Menstrual Cramps Relief Heat Patch with Wide Wings, FDA Registered - ThermaCare Menstrual Heating Pads – Portable, Adhesive HeatWraps for Period Cramps & Backache Relief, Discreet, Cord-Free Heat Therapy, Up to 8 Hours of Relief – HSA/FSA Eligible, (6 Count) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/494814489-sunnybay-heat-patches-for-menstrual-cramp-2-75x3-5-inch](https://www.desertcart.jp/products/494814489-sunnybay-heat-patches-for-menstrual-cramp-2-75x3-5-inch) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-10-23*
