## Customer Reviews

### ⭐⭐⭐⭐⭐ Good product
*by S***A on April 11, 2024*

Fits my holder

### ⭐⭐⭐⭐⭐ good quality at a great price!
*by N***A on December 26, 2018*

well and precisely made blades for the cutter i use practically for everything: house improvement works around, opening boxes and packages (some are really thick boards) and arts and crafts. the box the blades come in is also thoughtful in the way it opens and keeps the cap on (i always had the problem of losing the box caps before).

### ⭐⭐⭐⭐⭐ Sharp
*by J***R on September 25, 2023*

Replaced all of my utility knives blades with this kit. Works well.
