Custom Bubble Mailers

I love my logo on them, however I don’t like that there is a space when closing. The envelope part could have extended further, allowing for more packing room based on where the sticky tape is. I normally order bubble mailers from Amazon that are insulated, and I am able to take advantage of all the inside space, however they are not customizable. These mailers are good for just a few items but as a small business the larger size (which is what I really need) we’re just too expensive.
