I recently bought the above mentioned inserts.
As it turns out, i dont much like them. At least for me, they are a bit too flimsy for my likes. I was wondering if anyone knew the thickness of them. I have NOT been able to find that on the internet. I think they are 5mil, but have no way of telling. I only assume they are 5mil because i have some that i think are 10-15 that are thicker see how i logicaly came to my conclusion?
The package says 'Polyethylene Terephthalate' which is basicaly what Mylar is (at least a search under that chemical tells me it is made under the Mylar name)
I have done EXTENSIVE searching tonight for a mylar sleeve that is closer to 15mils thick. but have been hugley unsuccesfull.
Anyone know of a more rigid mylar sleeve?
