Clean and dry them first
This is the whole ballgame. A shell that isn’t fully clean and dry will smell — that low, fishy funk that turns up two days into the trip and follows you home. Rinse off sand and salt, then deal with any organic residue (a soak in a diluted bleach solution lifts the film and brightens the shell; vinegar can dull the finish, so go easy). Most important, let everything dry completely, ideally a day or two in the sun and air. Damp shells in a sealed bag are how you end up with a suitcase you can’t un-smell. Our shell-cleaning guide and remove-the-smell guide walk through it.
Cushion and pack
Once they’re dry, wrap them. Roll each fragile shell — thin jingles, brittle scallops, anything with delicate spines — in bubble wrap, a sock, or soft clothing. Nest the heavy stuff like a horse conch at the bottom and pad the light, breakable pieces on top. A small hard-sided container or a shoe inside your bag makes a great crush-proof shell box. The goal is simple: nothing rattles loose, nothing presses on a fragile edge.
Carry-on vs. checked
| Shell type | Best in | Why |
|---|---|---|
| Fragile (jingles, thin scallops, urchins) | Carry-on | Gentle handling, no crushing under bags |
| Sturdy (whelks, conchs, cockles) | Checked is fine | Tough enough to survive the hold |
| Heavy collection | Split the weight | Watch checked-bag weight limits |
| Sentimental / one-of-a-kind | Carry-on | You never lose what stays with you |
TSA has no problem with clean, empty shells in either bag, though a dense bag of shells can look odd on the scanner and occasionally gets a hand check — no big deal. Put the irreplaceable finds in your carry-on so they can’t get lost or crushed.
Pack only what's legal
One firm rule before anything goes in the bag: only empty, legally collected shells travel home. In Collier and Lee Counties it’s illegal to take a live shell, sand dollar or starfish, so if anything was alive when you found it, it stayed at the beach. See our Florida shelling rules. Do it right and your shelf back home becomes a permanent postcard from the Gulf — the kind of haul you bring back from a boat-only beach on one of our shelling tours.
From the Helm: The dockside packing trick we hand out at San Marco Marina
Back at San Marco Marina, before anyone's even peeled off a life jacket, one of our mates is usually handing out the day's haul in open paper bags instead of the zip-top bags guests brought from home. That single swap is most of the trick. A sealed plastic bag traps whatever moisture is still sitting in a shell, and a shell that flies home damp is a shell that starts smelling somewhere around baggage claim.
The mistake we correct most at the dock is guests wanting to pack straight from a wet bucket into a suitcase liner, shells still gritty and cool from the water they just came out of. We ask for ten more minutes — laid out on a towel in the sun at the stern while everyone else rinses off — before anything goes into paper, then newspaper or a spare t-shirt underneath for cushioning on the ride home.
For the genuinely fragile stuff, a paper-thin shell or a delicate urchin test, we keep a roll of bubble wrap tucked in the console specifically for that, because a piece like that riding loose in a checked bag rarely survives the baggage handlers. That one goes in a carry-on, wrapped twice over, sitting on top where a hand can check on it if the flight turns rough halfway home.
Sturdy shells — whelks, conchs, most bivalves — travel fine buried in the middle of checked luggage, where clothes do the cushioning for free the whole way. We tell guests to sort into two piles right there on the dock, tough and fragile, rather than sorting it out later at the hotel the night before a flight, half-packed and rushed with the clock running.
For guests carrying on only, with no checked bag at all, we scale the whole system down: one small zip pouch, everything wrapped in whatever soft layer's already in the daypack, and the sturdier pieces tucked into shoes instead of loose in a side pocket. It's the same tough-versus-fragile sort, just working with less room and needing a little more thought about where the pouch actually sits on the ride to the airport, ideally somewhere it won't get set down under a heavier bag at the gate or wedged beneath someone's carry-on in the overhead bin.
Only pack what you're legally allowed to carry off the beach in the first place — our guide to Florida's shelling rules covers that in full, and if you want a haul worth the extra suitcase space, booking one of our shelling tours remains the fastest way to fill one before you ever reach the dock.
