Ok, JyARman, this is for you and it's such a great idea that if you implement it in a future product, I want a piece of the action. You have a great product and there are other great containers on the market that claim an airtight seal as well, but yours as well as all the others have one great flaw and that is the air space within the container. Yours, like many others, while claiming to be airtight, still seals IN the air that is in the container, which is far from ideal. What is ideal, is that not only will the container seal out the outside air, but also will eliminate any air on the inside..................regardless how much bud is in the container thereby eliminating the need for different size containers. So with this in mind, check out the following product and see if you can produce this in a size and configuration of your current product line. I vision a very tight silicon seal that would down slide into the jar, thereby eliminating any air space and being that it slides down, it matters not how much bud is in the jar as the seal is totally variable. A little latch system to pull the seal out would have to be designed as well. Here's an example on a much larger scale being applied to a coffee bean container: http://www.paradiseroasters.com/air...medium=email&utm_term=Oct&utm_campaign=Geisha If this existed in the marketplace, I know that I would purchase it in a heartbeat.
