No issues at all. ### ⭐⭐⭐⭐⭐ Works Great *by T***R on October 7, 2024* works as it should, seems to be made well. No problems. ### ⭐⭐⭐⭐⭐ Good range of sizes for smaller volumes *by J***4 on November 20, 2024* I will use these to mix small batches of epoxy resin, using a magnetic stirring unit. Resin shouldn't stick to these, so I should be able to reuse them for a long time. This set should cover a range of epoxy volumes, so I can use with different mixing containers. For larger volumes, a drill with a silicone stirrer is better. ## Frequently Bought Together - CHSZCHC Magnetic Stir Bar Set,7pcs Lab Type-B Mixed Size PTFE Magnetic Stirrer Mixer Stir Bars - ONiLAB Glass Measuring Beaker Set 50ml 100ml 250ml 500ml 1000ml(Pack of 5) 3.3 Boro Griffin Low Form with Printed Graduation Scientific Glassware for Laboratories, Classrooms or Home Use --- ## 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/154542341-chszchc-magnetic-stir-bar-set-7pcs-lab-type-b-mixed](https://www.desertcart.jp/products/154542341-chszchc-magnetic-stir-bar-set-7pcs-lab-type-b-mixed) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-05-19*
