There's a lot of jargon in the merch world that doesn't really affect your purchase. Here's what you can skip:

• Drop number: This usually refers to the order in which releases happened, not the rarity of the item itself.
• Batch number: Often used for quality control, but it doesn't tell you how many were made.
• Serial number: This might be unique to your tee, but without a registry, it's meaningless.

Focus on the edition size and the authenticity markers. That's what matters.
