nice

### ⭐⭐⭐⭐⭐ Just what I needed
*by T***R on 23 July 2024*

Ordered these for a 3d printing project. They work a treat. Easy to insert using a soldering iron with a pointed tip in the middle. Takes a bit of practice to get them straight but that's the same for any brand of these. And they work just fine. Can't fault them - good value for a big bag full of inserts!
