## Questions & Answers

**Q: approx 3mm.... what is actual size?**
A: The actual size is 3mm inside diameter and 4mm outside diameter.  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

### ⭐⭐⭐⭐⭐ Review
*by J***S on 4 September 2019*

I needed to use these tubes to create a sleeve for stainless steel wire to slide through to pull on a latch to open a gate. These were perfect for that application. I bent it with a small-diameter tubing bender and they bent just fine without collapsing or narrowing their diameter.
