I think the reason they say "approximately 3mm", is because there will always be a (very) slight difference in the measurements on paper and in reality. Other than that, measurements are very accurate and the product so far has nice quality. **Q: Can you do lengths 3 x 750mm? internal diameter 7mm and external diameter as small as possible** A: No **Q: Is it magnetic?** A: No **Q: Could this be cut with an X-Acto knife?** A: No ## Customer Reviews ### ⭐⭐⭐⭐⭐ Funcionan bien *by C***S on 28 March 2023* Funcionan bien en nano_santizadora. ### ⭐⭐⭐⭐⭐ Perfect!!!!! *by T***W on 16 January 2021* ### ⭐⭐⭐⭐⭐ Just what I needed *by J***S on 4 September 2019* ## Frequently Bought Together - Eowpower 2 Pieces 304 Stainless Steel Capillary Metal Tube Tubing OD x ID, 4 x 3mm Length 250mm - Eowpower 5 Pieces 304 Stainless Steel Round Capillary Metal Tube Tubing Pipe 6 X 4 mm, OD x ID Length 30 cm - Eowpower 5 Pieces 304 Stainless Steel Round Capillary Metal Tube Tubing Pipe 3 X 2 mm, OD x ID Length 30 cm --- ## 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.hr/products/647701837-2pcs-304-stainless-steel-round-tube-tubing-od-x-id](https://www.desertcart.hr/products/647701837-2pcs-304-stainless-steel-round-tube-tubing-od-x-id) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-07-29*
