Large capacity, Sturdy construction
Size: 2 Gallon, Unit Count: 1.0
Very large capacity. Strong plastic construction. I use an auto injector once a week. This container will probably last me a year, yet it will easily fit in the sharps. Disposal receptacle in town.

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.
