I have 6"x20" 4 mil bags and their 6 mil liners. These are super thick, premium grade bags and are perfect for shipping fish that are known for puncturing bags, like discus and other spiney fish. I use them everytime I ship out an order of discus and I have never had a single leaky bag or DOA since switching to these from the much thinner 3 mil bags. I am selling them in 100 bag lots. The 6"x20" bags are $14 for 100 and the 6"x10" liners are $10 for 100. I use 2 bags and a liner (bag liner bag) for shipping fish. Or, if you already have 6" wide bags, but done need 4 mil bags, but want 6 mil liners, then these would work as well. Rely here, or send email to: OrlandoDiscus@gmail.com
