Don’t Throw Away Tuna Cans – At Home They’re Worth Their Weight in Gold! Here’s How to Reuse Them

We all love a quick and easy tuna salad or sandwich, but what happens to the can once the tuna’s gone? Most of us simply toss it into the recycling bin without a second thought. But wait — before you do, here’s something every household should know: those empty tuna cans are far more useful than you think.

In fact, with a little creativity and minimal effort, these small metal containers can be transformed into functional, decorative, and even eco-friendly items around your home. Think of them as mini treasures hiding in plain sight.

Here are some clever and practical ways to reuse tuna cans that will make you think twice before ever tossing one out again:
⇆
🔥 1. DIY Tealight or Candle Holders

Tuna cans are the perfect size for small candles. Clean them out, remove the label, and pour in melted wax with a wick to create your own custom candles. You can decorate the outside with jute rope, fabric, or paint for a rustic or modern touch. These make lovely gifts or cozy accents for your living room.
🧂 2. Magnetic Spice Containers

If you’re short on kitchen storage, turn your tuna cans into magnetic spice tins. Simply glue a small magnet to the back and stick them on your fridge or a magnetic board. Add a transparent lid (or use plastic wrap with a rubber band in a pinch) and label them. Now your spices are organized and accessible.
🌿 3. Mini Planters for Herbs or Succulents

Tuna cans make excellent mini planters. After cleaning them well, poke a few drainage holes in the bottom and fill with soil. They’re ideal for growing kitchen herbs, small succulents, or even starting seeds. Place them on a windowsill for a touch of greenery and a reminder of how resourceful you are.
🖼️ 4. Photo Frames or Shadow Boxes

Get crafty by turning tuna cans into mini shadow boxes or picture frames. Print out small photos and mount them inside the can. Add small decorative elements like dried flowers, fabric, or quotes for a unique wall or shelf display.

In the garage or shed, tuna cans are perfect for organizing small hardware. Mount them on a board or keep them in a drawer to neatly separate nails, screws, bolts, and other tiny items. They’re stackable and easy to label.
🎨 6. Kids’ Craft Organizer

Tuna cans are a great solution for organizing small art supplies like crayons, beads, buttons, or googly eyes. Attach several to a rotating tray or wooden board to create a craft caddy for your kids (or yourself!).
🎁 7. Eco-Friendly Gift Packaging

Looking for a unique way to present a small gift? Cleaned tuna cans make charming containers for homemade lip balms, cookies, or small trinkets. Just line them with tissue paper or fabric and add a ribbon. The container becomes part of the gift!
⚠️ Pro Tip: How to Clean Tuna Cans for Reuse

    Remove the label and glue residue by soaking in warm, soapy water.

    Wash thoroughly to eliminate any fishy odor.

    If needed, soak in vinegar and baking soda overnight to deodorize.

    Dry completely before using — especially if you plan to paint or glue anything to it.

With just a little creativity, tuna cans truly are worth their weight in gold.
