## Questions & Answers

**Q: Who cares about gallons? Please advise on all 3 sizes you sell in cm (width and length)**
A: Exactly! I don't fill my bags with fluid but stuff. 
Here's what I found:
Gals -- cms -- ins
0.5 -- 22.8 x 22 -- 9 x 9
1.0 -- 30.5 x 28.8 -- 12 x 11.4
2.5 -- 36.5 x 40.6 -- 14.4 x 16

**Q: What size would you recommend to use as a “slow cooker dump bag” ie put all ingredients in for meal, then freeze for future meal (taming twins recipe)**
A: I have never done this so I am guessing that you would need to use a large bag so as to fit all the ingredients in.

**Q: Do you have to remove all the air from the bag before freezing**
A: You don’t have to remove all the air out but I zip the bag nearly closed and squeeze any excess air out. These are good quality bags and can be reused.

**Q: Practically speaking, are these actually reusable?**
A: I tried doing a video but it won't upload because basically, these are the best food bags I've ever used. Very strong and if you turn them inside out to clean you can do a thorough job and leave to dry. I've o ly found they go wrinkly after being used in the freezer, but that hasn't remotely affected their quality. I'm still only on my second bag as I have reused each numerous times already.
