5×3×2" Box

Compact and rigid. Great for cassette tapes, digital cameras, small accessories, and any pocket-sized item that needs a proper box rather than a padded mailer.

🛒 Shop on Amazon → (opens in new tab)
📦
6×4×2" Box

Small and rectangular. Good for USB drives, small action figures, chargers, earbuds, and other compact accessories that need rigid protection instead of a padded envelope.

📦
6×5×1" Box

Very shallow and compact. Fits trading cards, collectible patches, small coins, jewelry, and flat fragile items that need rigid protection rather than just a sleeve.

🛒 Shop on Amazon → (opens in new tab)
📦
6×6×2" Box

Shallow square for small electronics, 8-tracks, cassettes, multiple CDs, and video game cartridges. Low profile keeps everything snug with minimal void fill.

📦
6×6×6" Box

The cube box. Perfect for mugs, small glassware, electronics, and bulk CD orders. Deep enough for a full layer of bubble wrap on all six sides.

🛒 Shop on Amazon → (opens in new tab)
📦
8×7×5" Box

Mid-depth square for compact electronics, small kitchen gadgets, action figures in packaging, and chunky collectibles. More cubic volume than it looks from the outside.

📦
9×6×1" Box

🛒 Shop on Amazon → (opens in new tab)
📦
11×9×2" Box

Wide and flat for tablet computers, photo frames, board game expansions, and flat artwork. The 11-inch length accommodates most standard tablets with room for padding.

🛒 Shop on Amazon → (opens in new tab)
📦
12×8×6" Box

Versatile mid-size for multiple books, some shoe styles, folded clothing, and smaller collectibles. Ample room for bubble wrap without going oversized.

🛒 Shop on Amazon → (opens in new tab)
📦
12×9×2" Box

Wide and flat for large tablets, framed photos, record albums, and oversized books. The 12×9 footprint accommodates items that don't quite fit an 11×9×2.

🛒 Shop on Amazon → (opens in new tab)
📦
12×10×2" Box

Wide and flat for large hardcovers, smaller board games, and flat puzzles. Low profile keeps shipping weight down even when the contents are dense.

🛒 Shop on Amazon → (opens in new tab)
📦
12×10×8" Box

Deep and roomy for adult shoe sizes, small appliances, stacked books, and bundled clothing. One of the most useful depths for items that don't fit a shallow box.

🛒 Shop on Amazon → (opens in new tab)
📦
13×10×2" Box

A hair wider than the 12×10×2, useful for oversized hardcovers or puzzles where that last inch matters. Also fits larger board game expansions neatly.

🛒 Shop on Amazon → (opens in new tab)
📦
16×12×8" Box

Counter appliances, gaming consoles, bulky clothing, mid-size electronics. One of the most common sizes stocked by high-volume eBay sellers for good reason.

🛒 Shop on Amazon → (opens in new tab)
📦
18×14×12" Box

Bulky items: small appliances, bundled clothing, sports equipment, and anything that doesn't fit a 16×12×8. A good next step up from that standard size.

🛒 Shop on Amazon → (opens in new tab)
📦
18×18×18" Box

Catch-all for large items: small appliances, globes, big glassware, anything that resists fitting elsewhere. Keep a few on hand for odd hauls.

🛒 Shop on Amazon → (opens in new tab)
📦
20×20×6" Box

Wide and shallow for large flat items: records in bulk, oversized puzzles, poster board, and shallow trays. The square footprint is hard to substitute with other sizes.

🛒 Shop on Amazon → (opens in new tab)
📦
20×20×20" Box

For large, heavy, or awkwardly shaped items that won't fit anything smaller. Check carrier dimensional weight — at this size it often matters more than actual weight.

🛒 Shop on Amazon → (opens in new tab)
📦
24×12×6" Box

Long and flat for full-size board games, large puzzles, framed prints, and rolled posters. The extra length is what makes it irreplaceable for this category.

🛒 Shop on Amazon → (opens in new tab)

Anti-Static Bubble Wrap

Required for anything static-sensitive: circuit boards, hard drives, RAM sticks, cassettes, and vintage media. Do not use standard bubble wrap on these. One discharge can kill a chip.

🌬️
Air Cushion Machine

A $100–$200 one-time investment. Cushions cost less than a penny each, store flat when deflated, and give buyers a premium unboxing experience. Far better than loose peanuts.

🛒 Shop on Amazon →

📦
Air Cushion Film Rolls

The consumable for your air cushion machine. Available in multiple widths and bubble sizes. Stock up on sale. Cost per cushion is a fraction of pre-inflated alternatives.

🛒 Shop on Amazon →

📄
Packing Paper / Newsprint Sheets

Safer than air cushions under heavy loads that can deflate them. Also great for wrapping glassware. Painter’s paper from a hardware store is a cheap bulk alternative; carriers accept it as long as all seams are taped.

📦

Always Use New Boxes

Reused boxes are often weaker than they appear. One damaged-item return more than pays for a pack of new corrugated boxes. Collectors in music and media categories are especially sensitive to this.

🎁

Shipping in the Original Box? Wrap It First

Large boxed items are often safe in their own packaging. Wrap the outside first. For big items, thick painter’s paper (hardware store roll section) is affordable and fully accepted by all major carriers as long as every seam is taped.

🛡️

Layer Your Protection

Small items: bubble wrap first, then poly bag inside the mailer. Fragile items: bubble wrap on all six sides so nothing touches the box wall directly. Anti-static wrap for anything with a circuit board.

Track Your Supply Levels

Running out of boxes mid-haul costs real time. Strooply’s supplies tracker lets you set custom restock alerts per item so you’re never caught short before a big listing session.
