What's a Mystery Chest?

A Mystery chest is a box filled with Kranite goodies! Each box is different, and there are new items every week. Chests can include:

  • Any retail item on
  • Prototypes or samples
  • Unusual finds from factory visits (like element samples)
  • Rare or unique items that are available through Mystery chests only
  • Imperfect items

Mystery chests are an exciting way to find some real treasure!

Why is there such a limited number?

We want to keep the value of the Mystery chests high, so we're keeping the numbers low. Opening a Mystery chest should always be an exciting, unexpected experience.

Types of Chests available:

$49 Small Chest
A small chest with at least 4 items. Expect at least $80 in retail value from the items.

$99 Chest!

A chest with at least 5 items ($170+ value)!

$499 High-Value Chest!

A chest with at least 8 items and at least one high-value item ($870+ value)!

Pleasantly surprised.

I am a rock/mineral collector and received 4 mineral/metals in this box which I did not have already. All in all it was great, some items I would not have bought on my own but okay. Would love to buy more boxes but am worried I will get duplicates of what I have already gotten!

Fun, like Christmas only metal :p

Was fun to open up and look through, cup looks to nice to use, but I'm sure I'll get around to it. Thank you for the excitement of opening it.

We really enjoy the mystery chest surprises, have purchased a few of them and they never disappoint! We’ve gotten a few pretty trick items, titanium sponge, really kewl teacups, even got a nice major tungsten cube and puzzle. It’s like Christmas!

Loved my surprises

Large Mystery Chest

Loved it! Full of very cool items (including Titanium and Copper) that far exceed the cost! I'll be buying these chests periodically from now on.

Very cool items

I received a mystery box recently after trying for months to order one. It’s a very popular item. Many of the items are useful and will be great gifts to others. Others will be cool to show my students in science class.

Surprisingly valuable

I’ve received 3 mystery chest and have a 4th on the way. They kept getting better than the last. I was surprised and pleased with how packed the boxes were and how fast they shipped. Bravo!

I've shopped online at many times and I've always had a terrific experience! Highly recommend Kranite to all who love beautiful and unique metal items and gifts.

Nice selection of "oddities"... several of which I was actually looking to purchase individually!

While advertised as odd and ends, scratch and dents, etc... I was pleasantly surprised with the quality of the selection and their condition (very good). I just may hit this up again, if offered again come Monday. :)
