When you get a product from Ultimate Guard, you don’t need to worry that it isn’t well made. Besides, they always have quite reasonable prices, which is great.


ChromiaSkin is the name for the surface of those deck boxes, which is heat sensitive. It doesn’t change just because you touch it, but because of temperature difference. So if you’d take it with you to a sauna, it would also change colors.

Here’s some info about when the color changes:

  • Original Color: under 19°C / 66°F
  • Optimal for a Change: around 26°C / 79°F
  • Fully Changed Color: 36°C / 97°F

So if you live in a very cold place, the deck box would need to be held for a longer period of time to change colors.


Sindwinder is a type of Ultimate Guard deck box, where the deck lies on its side. The inside edge of the deck box is curved in a way that enables easy access to the deck, as can be seen on the picture below.

You can get this deck box in two sizes: 80+ and 100+. Here’s their dimensions and how many cards each of them holds.

So how good those deck boxes actually are? Let’s first talk about the quality of the deck box and forget whole changing colors thing. If your deck box can’t safely hold your cards it doesn’t matter how pretty it is, right?

Thankfully, the deck box is very well put together. It’s stitched together very nicely and it likely won’t fall apart even after using it for multiple years. The inside is made from a soft material, which is great for your cards.

Four strong magnets hold the box together and they produce that satisfying click, when you close it. Even after the shake test the deck box doesn’t open, so it’s safe to say that it won’t open randomly in your back pack.

All in all, the deck box is on par with the high standards of quality of the Ultimate Guard and will definitely serve you for a long time.


Okay, so ChromiaSkin is probably the reason why this deck box caught your eye. How good is it in practice? Well, in most places the deck box work as advertised. Everywhere someone touches it, it changes colors.

Otherwise the color changes are really cool looking, although maybe not as drastic as some promotional pictures suggest.
