More Than Just Coins
Despite the name, "coin envelopes" are the backbone of small parts organization across multiple industries. Made from breathable, unbleached kraft paper, they are the standard choice for agricultural seeds, jewelry, resistors, and heavy hardware parts.
Understanding the Sizing Standard
If you are purchasing in bulk, it's crucial to order the correct industry-standard size. Here is a quick reference guide:
#2 Coin Envelope (2.25" x 3.5"): The smallest standard size. Perfect for tiny electronic components, memory cards, and individual flower seeds.
#4 Coin Envelope (2.5" x 4.25"): Slightly longer, ideal for jewelry findings, watch parts, and sorting screws/nails in hardware kits.
#6 Coin Envelope (3.125" x 5.5"): A mid-size option frequently used for cash handling, larger agricultural seeds, and optical lenses.
#8 Coin Envelope (3.5" x 6.5"): The largest standard coin size. Great for small booklets, receipts, and heavy-duty industrial sorting.
