Extremely Useful and Great to Have Everywhere!
This 8-pack of utility knives has been surprisingly handy! I originally bought them for opening packages, but now I keep one in the kitchen, office, garage, and even the car. They’re lightweight, compact, and the retractable blades make them safe to store anywhere. The 9mm blades are sharp and perfect for all kinds of tasks — breaking down boxes, cutting paper, doing small craft projects, and opening packaging without damaging what’s inside. I love that they come in multiple colors so everyone in the house can easily grab their own. For the price, this is a fantastic value. These cutters are useful, reliable, and perfect to have on hand for everyday jobs. Highly recommend if you want simple, effective box cutters that just get the job done!

The Best!
I have used many brands of these mini snap blade utility knives, including sets from dollar tree, till they quit carrying them. Recently, an expensive regular size utility knife i had, quit retracting, and became unusable, so had to throw that out. Decided to try these mini knives; so glad I did! Can't beat the price for a set of $5.99 for an 8 pack. Love the bright colors too. These are super sharp, strong, durable, the blade retracts smoothly and easily. I have used these for opening packages (cardboard boxes,) and they cut right through the tape holding the box together, (easy to fold the cardboard for recycling the box.) Wonderful product, probably won't need to order more for awhile; still on one knife from the set I ordered,. Love the snap blades; saves money and time having to buy blades separately and put into knife. I use a pair of snip nose pliers to snap the perforated blade off when it becomes dull, and continue to use knife with new blade. What a handy little tool! I prefer these mini utility knifes to the regular/larger sized knives. Bravo DIYSELF!

Cheap, Cheerful, and Cuts… Mostly Light Stuff
Very lightweight and easy to use. The 9 mm blade is sharp enough for everyday tasks like opening boxes, cutting paper, and light craft work. Don’t expect it to survive a lifelong battle with heavy-duty cardboard, but for the price, it does the job. Retractable blade adds safety, and the different colors are surprisingly useful in an office. Cheap, practical, and honest about what it is — just don’t ask it to be a superhero.

Good product.
Just what I needed. Luckily it wasn’t windy the day of delivery or the package would have blown off the porch . Seems the delivery guys don’t like to use a mail box
