Review on 🔥 2 Pack Leather Burnisher Bits for Dremel Tools - Pointed Head Leather Craft Tool Set: Create Clean and Smooth Edges on Projects by Hannah Curi

I bought it and only used it for a few seconds starting with the big one, it was unbalanced and vibrated badly at low speed, wouldn't try any other speed knew what would be worse, replaced it with a small one and started using it even at slow speed, also vibrated a lot, i use it at slow speed for maybe 30 seconds when the shaft bent and my thumb very hard hit , it hurts like MFer , the shaft is bent almost 90 degrees. As such, they are unbalanced, have weak staffs, and are dangerous.
