Reliable sharps container.
Solid, reliable sharps container for home use. The lid locks securely and gives peace of mind, especially with kids around. It’s sturdy, holds a good amount, and doesn’t take up much space. Exactly what I needed, simple and safe.

Size matters
Have a nice container that can holds a lot but not so tall and skinny like most to the point that their top heavy and tip over. I feel like this one has the balance between being large without taking a too much space and also holding a lot

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.
