very sturdy
I got these to make craft kits to sell at a market. They have been really sturdy and have held up to being packed and handled by customers ( no tears or anything). They zip open and close easily, but stay closed, and are translucent . I made directions on 8 x 11 paper, and cut in half, and the paper fit into the bags perfectly. At about 3 cents each, they seem like a really good value and will hold up to re-use. I plan to buy more.

Great storage bags
I bought these to store my Ottobre pattern magazines in. They fit perfect and are jus the right size. These bags are thick and not cheap feeling. The zipper part is strong as well. I take my magazines out of the bags frequently to browse and use and I’ve not had one bag rip yet.Love them!** UPDATE 11/12/13 ** I loved these bags so much I came back to order more. However, the first order I received from “Court House Supplies” was terrible quality. The bags were thin and scratchy feeling. I sent them back and re-re-ordered from my original supplier “Collecting Warehouse”. I received the awesome bags I love so much. They are smooth feeling, thick, and have a white strip where the Ziploc part is. Make sure you get the good bags! Order from the right supplier!

Great multi-purpose bags!
I love these bags as well as their price. I originally bought them for filing papers, but am now using them for freezing produce as they are food safe. The strip at the top works well to close & open bag. So far I haven’t had any problems with their durability. For travel I’ll use them for loose vitamins, and for costume jewelry.

Love ’em. They are perfect
Love ’em. They are perfect. Just like the Ziploc freezer bags but of course way way cheaper. Very sturdy thick plastic, even thicker than Ziploc’s. Completely water tight. I’ll never buy another ziploc. My only complaint was that there were some knife slashes in the first 3 at the top of the pack. I thought well damn I’ll have to return these. But it turned out to be just the top 3 which left me with 97 more. I didn’t have a problem with that.

These are fine and measure as stated
First, this is not what I have received. The printing on mine is as follows: RELOC / ZIPPIT, reclosable 100 Bags 9 x 12 4 mil. These are fine and measure as stated. I had another inquiry on this item where the customer stated that the bag sizes were not as advertised. Again, what your picture shows is not what I have.I don’t use these for food storage. I ordered them in the hope that I could store 1 gallon opened paint cans in them. However they are too narrow for that purpose, thus my 4 star rating. I order a larger size, I think 13 x 18 which do meet my needs. Either way, the 9 x 12 I have are fine.

Nice “Zip lock” bags
These bags are slightly larger than the gallon size of those famous brand “ZipLoc” bags and have slightly different dimensions. I purchased them because I could use them to protect a full size sheet of 8.5″ x 11″ printer paper. Those other gallon size bags will do that too but you can’t “zip” ’em up after you put the paper in. They’ve proven to be useful for a lot of other things too including storing food because they’re made of food grade plastic. The bags are quite sturdy and have a strong, reliable closure.

Great for many uses
These are the perfect bags for what I need and because they are a bit heavier than standard baggies have been put to use to hold everything from documents to nuts and bolts. They’re an item I repurchase regularly.
