Our Neptune simple capped cornerstone time capsule box measures a full 12x12x24" on the inside. The standard cap measures 12x12". This time capsule box has a capacity of 3456 cubic inches or 2 cubic feet. Although dependent on the actual size of your items, the Neptune size holds up to about 425 standard document type items.
Your capped cornerstone order includes the following items at no additional charge. For more supplies to protect items, order a preservation kit or separate packages appropriate to your items.
The time capsule is air tight after sealing. It is made of low corrosion stainless steel. It has a satin finish with welds polished smooth. It is water resistant, but should not be sitting in water over a period of 2 weeks (provide a way for the water to drain away). While its expected life is 75 years, the longevity of the time capsule protection can be more or less, depending upon the customer's conditions of placement. Use common sense and read all instructions that come with your purchase.All of our box time capsules come with sufficient packing to protect them from damage in transit. The packing may include foam insulation panels. You may place these panels around the outside of the time capsule while in placement. The R value is not high, however, so especially if you place the capsule near any outside wall, you need to think about how much insulation you need for your conditions, and add more if necessary for that placement.
