I purchased this so I could store a full-sized air mattress. It fits perfectly! Probably won't once I use it and try to refold it tho. It's a very tight fit. As far as a tool bag, it's OK. I just got one from Harbor Freight for $7 and it has a bunch of pockets and is thicker. Go get that one. :)This tool bag is ideal for someone who needs a tool bag that is not only durable but is also very reasonably priced. Great size for the handyman/woman who doesn't have a ton of tools but needs to keep everything in one convenient place!La calidad deja mucho que desear, si buscas una maleta simple solo para almacenamiento de llaves en casa funciona, pero no la recomiendo para trabajo pesado en campo de andar sacando y metiendo porque seguramente se romperia.Not fit for tools. Maybe be good for a garden tool bag.I wanted this for dog sport supplies, so it wasn't holding anything heavy. Still sucked. Very cheap, annoying to try and zip up. I threw it out.Nice rubber bottom incase i drop it on an inch of waterGood quality
