These are American letter size not A4 as advertised. The quality is excellent, but description is incorrect

Bon rapport qualité prix

Llegaron muy rápido, muy bien empacados. Son de un plástico resistente, las anillas embonan perfectamente y se mantienen firmes incluso con mucho peso, el plástico de las ventanas exteriores vienen unidos a cada cara lo cual dificulta un poco meter el papel para la portada, contraportada y lomo, pero igualmente eso es lo que mantiene una excelente presentación al ya haberlas metido.

The folders are very strong and durable. But the size was too small. Even A4 size papers barely make it. Disappointed with this. Please look for something bigger

IOW, a good value for the price. They appear to be durable, but only time will tell. And they do appear to be sturdy, what with the dozens / hundreds that I have purchased over my 71 years of life; I feel that I am a good judge. And the 4 are replacing some that lived a good life.And I have over 60 binders in barrister bookcases, which basically chronicle my like as a hobbyist working with my hands and brain who has worked with steel, copper, aluminium, wood, plastic, and electronics. Basically the gamut of the physical sciences and materials; mostly combined in the same projects.I have a saying, I don't really own an object until I have modified it (or hacked it), that is my nature and what drives me into retirement. Cars are to damn expensive as a hobby, so the last 20 years or so it has been computers and furniture that I build and 'hack'.20 years ago I designed and built a fixture for assembling and operating a PC outside of the case; and sold a few dozen until the Chinese and Taiwan companies came out with similar products. Well I did enjoy the first 5 years I was doing it as more of a hobby, so "no crying over spilt milk". And I still occasionally build a new fixture from materials that I still have around. Yes, I admit (and with pride) to being a hoarderer. And with pride I say that I have also done some 'dumpster diving' late at night behind RadioShack stores (and that reference 'dates me'); along with a few local consumer electronics stores.And yes I have been arrested once; but was let go quickly when another local cop vouched for me as knowing me from my PT pre-retirement RadioShack sales job. He was a customer of mine for a few years back then. And recognized my 'hacked' 30-plus yo 4Wd Toyota PU (midwest road salt did it in as with all Japanese vehicles in the 60's thru the late 1980's). Hell, it was unsightly after only 5 years. But by driving it all winter, I was able to keep my 1985 Corolla GTS Twin Cam 16 valve Coupe in the garage all winter sonic could get over 30 rust free years out of it. And that GTS was best driven at speeds in excess of interstate speed limits ... and have enough power to spin the rear tires on a 1 to 2 shift in town. But I did replace tires like every 10,000 miles routinely. But only drove it like 4,000 miles each year, like maybe 6 months each year. 2nd best (and 2nd funnest car I ever owned) - the best was my first, a 1969 Z-28 Camaro after serving in the US Naval Air Reserve. In which [@ 18 yo] this fool kept his foot in it until the speedo got back to 0 MPH = 160 MPH and the tach @ 8000 RPM! But course I had to fix it after that, the rocker arm studs started slowly coming out. Hell it barely had 4000 miles on it then; but I enjoyed fixing it and having the local speed shop fix the heads properly. And next year 70 1/2 new version got the same threaded in rocker studs that I had the shop install. By GM also got rid of solid cam, so no more 7200 rpm redline any more; IMO they castrated the fun-factor out of that motor. But hey, part of the timing was emission control laws to clean up the exhaust gases. I guess people in California got tired of living under a blanket of smog ....Yep, way off the topic of binders ...
