1- Kraft Bubble Mailers 3.4×5.5 Padded Envelope

Our top pick are these 3.4 x 5.5 inch Kraft bubble mailers. They come in a bulk lot of 500 which is perfect if you have multiple cards to either sell or grade. They are literally the perfect size for sports cards. This high quality padded envelope is able to fit one top loaded sports card with a snug fit.

The inside is fully laminated with provides extra stiffness. The bottom of the envelope also has a seamless bottom which provides additional protection with a small air cell cushion. This greatly improves the overall structure strength of the envelopes. Sealing the mailer is as easy as peeling off a sleeve and sealing it with its built in adhesive strip.

2- Fuxury 4×8 Kraft Bubble Mailers Padded Envelopes

The next bubble mailers on our list are these kraft bubble mailers by Fuxury. They are slightly bigger than the previous mailers, but will work just as well. They measure at 4×8 inches and come in a pack of 50 mailers and are decently priced.

For convenience, each mail comes with a strong self-sealing adhesive strip. Simply remove the strip and fold over the seal to securely seal your mailer. Always be sure to double check the seal as I have personally had mailers that were not very sticky and ended up opening shorty after.

Each mailer is also built to withstand rigorous shipping and handling as well as being tamper resistant. On the inside are thick bubbles that take quite a bit of force to pop. Many low quality and cheap bubble mailers have bubbles that are not completely full of air, or have a cheap plastic that rips or tears easily.

The overall reviews from verified customers are extremely positive. These are high quality mailers that you can rely on to safely transport your items. However, there are a few complaints that the quality control has plummeted recently. It can be a hit or miss if you get a good or a bad batch.

What we like

  • High quality
  • Good Price
  • Built in stick and seal
  • Thick bubbles
  • Lightweight

What we don’t like

  • Quality control issues
  • Not a good size for multiple cards

4- 3.5X5.9 Inches Small Padded Envelopes Poly Bubble Mailers

The next mailers on our list are 3.5X5.9 Inches Small Padded Envelopes Poly Bubble Mailers. The first thing that stands out from these bubble mailers are that they are colored. At this time, they can be purchased in both black and pink. This gives a little customization to your shipping and does not affect the overall integrity or strength of these.

On the outside they also offer a self adhering seal. This is probably one of the most important aspects to look for in a bubble mailer after the quality. Having a self adhering seal will greatly reduce the amount of time that it takes to ship items in bulk.

The overall quality of these envelopes are high. The inside is cushioned and the envelopes are lined with 80gsm bubble.

The overall review of these envelopes from customers is positive. However, some of the negative remarks were based on the colors of these envelopes. The colors are not always consistent with what is shown in the listing.

Again, on the outside is a self sealing adhesive which makes shipping and packing quick and easy.

What to Look for in a Bubble Mailer

To find the best bubble mailer for your needs, consider the following major aspects before finalizing a purchase.


Bubble mailers come in a variety of sizes and dimensions. You will be charged based on the weight as well as the dimensions of the mailer you use, so using the smallest mailer possible will help cut costs from shipping.

If you are sending a single sports card inside of a top loader, then we recommend using a bubble mailer with a size of at least 3.4×5.5 inches. If you will be sending in multiple cards, then we recommend going with a small box or a much larger bubble mailer.


Using a high quality bubble mailer will ensure the arrival of your product in one piece to its destination. Some cheaper mailers will feel flimsy, have very weak bubbles, and will also rip or tear easily at the sides.

We recommend using a high quality bubble mailer, especially if you are sending in extremely valuable cards. During the shipping process, your package may be roughly handled, and having a strong mailer will help prevent and accidental damage during shipment.

High quality bubble mailers will usually have thick and hard to pop bubbles, along with a durable outside that is not prone to easily ripping or tearing.


Bubble mailers can generally come in a variety of styles and colors. Choosing a style and color is mostly personal preference, but the generally accepted colors are white and bright yellow.

Best Bubble Mailer Brands


When it comes to shipping materials, Uline is the leading distributor. They have been providing shipping services and products for over 40 years now. They have some of the best products available on the market. The real drawback to their products can be the price.

Many of their shipping products are priced higher than their competition which can make it less cost effective or profitable to purchase shipping supplies from Uline.


How Do You Send Sports Cards in a Bubble Mailer?

The first step is packaging your sports card. The best way to do this is to first place your sports card in a top loader, or by sandwiching the card in between two small pieces of cardboard. This will give added protection to your card while it is inside the bubble mailer.

The next thing you have to do is purchase shipping. Purchasing shipping can be done through the platform you are selling on or, if you are sending something out yourself, you can use a third party shipping service for lower shipping rates.

We recommend using a platform like to purchase labels at a discounted rate. Purchasing shipping through a platform will always be cheaper than buying shipping yourself.

The weight and dimensions will need to be taken of your item to get an accurate price for your shipping label.

Are Bubble Mailers Safe for Sports Cards?

Bubble mailers are safe for sports cards as long as the proper handling is done before hand. Always be sure to protect your cards before placing them inside a bubble mailer. This is a very important step that cannot be skipped or you could potentially end up with a damaged card.

Final Thoughts

Our top pick is the Kraft Bubble Mailers 3.4×5.5 Padded Envelopes. They are the perfect size for single sports cards that are inside of a top loader. They offer a completely cushioned inside with a liner and air bubbles for maximum protection. On the outside is a self seal. Simply remove the plastic on the adhesive seal to expose the adhesive. Seal it by simply closing the flap.

Our runner up is the Fuxury 4×8 Kraft Bubble Mailers Padded Envelopes. They are just about as good as our top pick, but quality control can be a slight issue. These are also slightly more expensive, but if you are not looking to spend a lot of money on a bulk lot, then these are your best bet.

Whichever bubble mailer you choose for your sports cards, we hope this guide has been helpful in your purchasing decision. Thanks for reading!
