Featuring 3 flexible stainless steel blades and a smart foil design, it adapts to facial contours and hair growth directions for a fast, close, and comfortable shave. Designed for durability, it efficiently cuts up to 6 million hairs and should be replaced every 18 months to maintain optimal performance. Easy to install, it restores your shaver’s peak functionality and skin-friendly experience. ## Description Small investment, peak performance: Within 18 months your series 3 electric shaver will cut an average of 6,000,000 hairs. In accomplishing this substantial task, the cutting parts will gradually wear out and your shave may become less close and comfortable. That’s why we recommends changing your shaver’s foil and cutter block every 18 months to maintain your shaver’s maximum performance. For a perfect shave every day. How to replace your shave head: For older models which have a foil and a cutter block as two independent parts, you will need to change the parts in two steps: 1.First remove the foil, either by pressing the release button if you shaver has one, or by pulling the foil. 2.Next rotate the cutter block by 90 degrees and pull it off, holding it at the ends to avoid touching the blades. 3.To fit new parts, simply carry out the same procedure in reverse. ## Features - Fit & Work Perfectly: 21B Series 3 replacement head fits Braun electric foil razors 300s, 310s, 3010BT and all series 3 shavers. - Efficient & Fast Shave: the head includes 3 flexible blades that adapt to your facial contours for a greater comfort and flawless finish. - Adaptive Shaving: with pressure-sensitive blades that automatically retract to protect your skin, just shave it free and clean. - Rapid Closeness, Smart Foil: unique foil pattern captures hairs growing from different directions for a close shave in fewer strokes. - Small Investment, Peak Performance: to maintain best shave, we recommend to replace the shaver head every 18 months. ## Technical Specifications | Specification | Value | |---------------|-------| | Asin | B0CB3DTTWW | | Best Sellers Rank | #988 in Men's Electric Shavers | | Date First Available | 14 July 2023 | | Item Model Number | 21B S3 | | Manufacturer | TEEYSO LLC | | Package Dimensions | 6.2 x 3.99 x 2.39 cm; 9 g | ## Product Details - **Brand:** TEEYSO - **Number of Items:** 1 - **Number of blades:** 3 - **Recommended uses for product:** Beard - **Unit count:** 1.0 Count ## Images ![Series 3 Replacement Head for Braun Electric Shaver -21B- Compatible with Braun Electric Razors 300s, 310s, 3010BT (1 Pack) - Image 1](https://m.media-amazon.com/images/I/71vNprh9AXL.jpg) ![Series 3 Replacement Head for Braun Electric Shaver -21B- Compatible with Braun Electric Razors 300s, 310s, 3010BT (1 Pack) - Image 2](https://m.media-amazon.com/images/I/71Pf8dqSswL.jpg) ![Series 3 Replacement Head for Braun Electric Shaver -21B- Compatible with Braun Electric Razors 300s, 310s, 3010BT (1 Pack) - Image 3](https://m.media-amazon.com/images/I/71vIEAu-4RL.jpg) ![Series 3 Replacement Head for Braun Electric Shaver -21B- Compatible with Braun Electric Razors 300s, 310s, 3010BT (1 Pack) - Image 4](https://m.media-amazon.com/images/I/819qEX6z1HL.jpg) ![Series 3 Replacement Head for Braun Electric Shaver -21B- Compatible with Braun Electric Razors 300s, 310s, 3010BT (1 Pack) - Image 5](https://m.media-amazon.com/images/I/719UCaDGrFL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works well. value for money *by on Reviewed in the United States 8 September 2025* Works well. value for money ### ⭐⭐⭐⭐⭐ Replacement razor head *by on Reviewed in the United States 21 March 2024* Perfect blades for my husband's razor. ### ⭐⭐⭐⭐⭐ fits as described *by on Reviewed in the United States 6 August 2026* cheaper than buying a new razor ## Frequently Bought Together - Series 3 Replacement Head for Braun Electric Shaver -21B- Compatible with Braun Electric Razors 300s, 310s, 3010BT (1 Pack) - Braun Electric Razor for Men, Series 3 310s Electric Foil Shaver, Rechargeable, Wet & Dry - Yinke Case for Braun Series 3/ Series 5, 3040s, 3010S, 5018s, 5140s Electric Razor Shaver, Hard Travel Case Protective Cover Storage Bag (Black interior) --- ## 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.kr/products/618742279-series-3-replacement-head-for-braun-electric-shaver-21b-compatible](https://www.desertcart.kr/products/618742279-series-3-replacement-head-for-braun-electric-shaver-21b-compatible) --- *Product available on Desertcart South Korea* *Store origin: KR* *Last updated: 2026-10-28*
