What each format is
A tube groups several identical coins in a plastic capsule. A monster box brings several tubes together in a sealed mint box, with its marks and its seal.
Why the seal matters
A box that is unopened and has its original seal is easier to verify and to resell. If the seal is broken, the listing must say so, and the price reflects it.
Weight and shipping
A monster box weighs several kilos. Shipping is calculated at the end, in the cart, and is insured until confirmed delivery. Check the weight carefully before buying.
What to do when you receive it
Record the unboxing video of the package without cuts. It is required to file a claim, and you have five days from delivery.
How many units
The listing states how many tubes the box holds, how many coins each tube holds and whether the seal is intact. Compare the price per coin and not only the total price.
