Exactly as expected.
Size: 5 Quart, Unit Count: 1.0
Exactly what it is made for. It is a perfect size for months worth of needles that we are using for our peptide injections.

Works and safe!
Size: 5 Quart, Unit Count: 1.0
Good sharps container. Fits typical diabetic syringes perfectly. It also fits zepbound auto-injection pens, but they are a little more difficult to cram into the opening so I took off a star for that.

Excellent size
Excellent for prescription needle disposal. The containers provided by my pharmacy are too small and don't hold all of my used prescription supplies. Lid closes easily and keeps everyone safe from accidental insulin injections!

XS fit well 5’3” 105lbs.
Size: X-Small, Color: Ceil Blue
Ordered these in XS. I’m 5’3” 105lbs and always buy pants in petite length. I’m around a 26” waist. The drawstring makes the pants easily adjustable and the length is a little long but will be fine with thicker sneakers on. Will be keeping! And I love the neon orange drawstring.
