    Product Overview

    Flat Boxes from Thy Custom Boxes are your simple answer for shipping and storing stuff. These boxes arrive at your place completely flat. This saves you space because you don't have to store bulky, already made boxes. When you need one, you just fold it up! It's like magic, but it's just good design. We make our Flat Boxes from strong cardboard material. This means they can handle getting bumped around during shipping. They are tough enough to protect your items from getting damaged. We want to make sure your things arrive safely to their destination, or stay safe in your storage area. These boxes are really easy to put together. You don't need any tape or glue to build them. Just follow the simple instructions printed on the box. It's like putting together a puzzle, but much easier. Anyone can do it in just a few seconds! This saves you time and effort when you're trying to pack things. Thy Custom Boxes offers Flat Boxes in many different sizes. This means you can find the perfect box for whatever you need to pack. Whether it's books, clothes, or small electronics, we have a size that will work for you. Check out our size chart to find the box that fits your needs perfectly. Using Flat Boxes is also better for the environment. Because they ship flat, we can fit more boxes on a truck. This means fewer trucks on the road, which reduces pollution. Plus, cardboard is recyclable, so you can feel good about using our boxes. Thy Custom Boxes wants to provide packaging that helps protect the earth. We believe this is a very important responsibility. Choose Flat Boxes for simple, strong, and environmentally friendly packaging.

    Learn More About Flat Boxes

    Flat Boxes from Thy Custom Boxes are like magic envelopes for your stuff. They start out completely flat, like a big piece of cardboard, but they quickly fold into a sturdy box. Think of them as origami, but for packaging. They are super useful for sending things in the mail, storing items, or even making crafts.

    What are Flat Boxes?

    These boxes are made from strong cardboard, the kind that can protect your things during shipping. The cardboard is scored, meaning it has lines that make it easy to fold in just the right places. You don't need any glue or tape to put most of them together because they have special flaps and tabs that lock together. It's like a puzzle that makes a box. When you are done using them, you can easily flatten them again for storage, which saves a lot of space.

    Why Choose Flat Boxes from Thy Custom Boxes?

    Thy Custom Boxes makes these boxes with a few important things in mind. First, we want them to be strong. We use good quality cardboard that can handle being tossed around during shipping. Second, we want them to be easy to use. The folding process is simple, and most people can figure it out without instructions. Third, we want them to be affordable. We know that packaging can be expensive, so we try to keep our prices low. Finally, we care about the environment. Our cardboard is made from recycled materials, and the boxes are recyclable too. So, you can feel good about using them.

    How to Use Flat Boxes

    Using a Flat Box is very simple. Start by laying the box flat on a table or the floor. You will see the score lines, which are the lines that have been pressed into the cardboard to make it easier to fold. Fold along these lines, following the instructions printed on some of the boxes, or just by looking at the shape of the box. Tuck the flaps and tabs into the slots to lock the box together. If you are shipping something fragile, you might want to add some padding inside, like bubble wrap or packing peanuts. Once your item is inside, close the top flaps and seal the box with tape if needed. Write the address clearly on the outside, and you are ready to ship!

    Sizes and Shapes

    Flat Boxes from Thy Custom Boxes come in many sizes and shapes. We have small boxes for jewelry or small electronics, medium boxes for books or clothes, and large boxes for bigger items. We also have different shapes, like square boxes, rectangular boxes, and even some special shapes for specific items. The best way to find the right size for your needs is to measure the item you want to ship or store, and then choose a box that is slightly bigger. This will give you some room for padding to protect your item.

    What Can You Use Flat Boxes For?

    The possibilities are endless! You can use them for sending gifts to friends and family. They are perfect for small businesses that need to ship products to customers. You can use them for storing your seasonal decorations, like Christmas ornaments or Halloween costumes. They are also great for moving things from one place to another. Artists can use them for shipping artwork. Students can use them for storing school projects. Really, any time you need a box, a Flat Box can be the perfect solution.

    Benefits of Using Flat Boxes

    There are many benefits to using Flat Boxes. They save space because they can be stored flat when not in use. They are easy to assemble, so you don't have to spend a lot of time putting them together. They are strong and durable, so they can protect your items during shipping or storage. They are affordable, so you don't have to break the bank to get the packaging you need. They are environmentally friendly because they are made from recycled materials and are recyclable.

    Taking Care of Your Flat Boxes

    To keep your Flat Boxes in good condition, store them in a dry place. Avoid getting them wet, as this can weaken the cardboard. If you are reusing a box, make sure it is still in good condition before using it again. Remove any old labels or tape, and reinforce any weak spots with new tape. If a box is damaged, it is best to recycle it and get a new one. When you are finished with your Flat Boxes, please recycle them so that the materials can be used again. By taking care of your boxes and recycling them, you are helping to protect the environment.
