You will receive 1 Cosmetic key and can redeem it at /warp crates

Items within this crate are retextured variants of existing Minecraft items. Hovering over an item in the crate will show you which base item the cosmetic takes it's stats from.
For example, The "Frog Plushie" is a item with a custom skin. This only works to change the appearance of the item and not the original item's stats.

Chances for all items can be found in-game in the crate GUI and will always equal 100% when combined
