The honeywell vault and its size

I went to the mall yesterday to check the actual size of the safety vault that I like and this is the actual size of it.

outside diameter: 26.2"H x 18.3"W x 20.12"D

Inside diameter: 18.5" H x 12.8"W x 13.18"D

The brand of the safety vault is Honeywell. This name has a lot of design and sizes to choose from depending on the preferences of the user and its budget because most of this items are quite costly.
