6 pack Mini Portable Utility Office Keychain with auto Retractable Blade Pocket Knives Letter Opener Small Box Cutter (MIX COLOUR 6PCS)

I use it at work. Not bad.

Great for slicing the packing tape used to seal boxes, not really made to cut through the actual corrugated cardboard.

These are great! They are small enough to keep one on your keychain. I have some a the office, in the car, and at home. Great size, easy to use. The blade retracts back into it's case quickly so you don't cut yourself.

Very compact and handy, but one drawback is that the blade does not lock into placewhile cutting. If you do not hold down the extend button, the blade retracts.

Came in good packaging and in its on zipper bag. Fits perfectly in my husbands pocket and on my wrist bracelet at work. Very sharp and cuts through cardboard and tape like nothin. Recommend for anyone who opens packages on the daily.

Good value for handy item.

Wish they came in key rings instead of the chains since the chains break, and I wish they had replacement blades. The blades are sharp though! These are super convenient.

I'm very happy with these little blades! They are exactly what I'm looking for! I read the description carefully and was happy to find out that the blades auto retract. I work in retail and the cutting tool my company gave us is very large and bulky and doesn't fit on a keychain. Some bought blades but they don't auto retract and the boss doesn't agree with us using them for safety reasons. These are perfect! They are a great price, too. As part of a Christmas gift, I plan on removing the chain and attaching each one to their own retractable badge holder. Thank you.
