Ive had these and the black coloured toaster bags and the black ones are superior in every way, they are wider which means you dont have to smash your sandwich up to fit it in the bag, which you have to with these.
I bought 3 packs of JML bags and had to return 2 of them because they were made with the handle holes at the bottom so were totally un-usable.
JML hve now stopped producing these bags - possibly due to all the errors they made manafacturing them.
The black bags as i said are wider so sandwiches drop in easily, the material is also a lot thicker and they are taller - so less likely to burn you than these shorter narrower bags
