There are multiple reasons why we only have certain designs on our bubble mailers. The main factors are price, storage, and rate of sale. Bubble mailers cost significantly more to produce and sell slower than our popular and fastest selling poly mailers. 1 box of 600 6x9' bubble mailers takes up the same space as roughly 10,000 6x9' poly mailers. Although we have grown our warehouse space significantly over the year, it's hard for us to store that amount of inventory as a small business. We will continue to add bubble mailers with different designs, but we continue to only have a few select designs for those.
