I think it's funny that these are marketed as incontinence bags. They're literally large polymailer...you know, to ship stuff. I have been using these (or similar bags) to ship items for years. They work great for that purpose. They're very hard to puncture. The sticky tape seals nicely. I haven't had any complaints about them. The price is right on for 200 polymailers, about what I've paid in the past. Yeah, I guess they could be used as incontinence bags, since they seal and all, but why would you? They did not have a smell to me, maybe a light plastic smell that all polymailers have, but nothing terrible.200 Pack Adult Diaper Disposal Bags,Gray Disposable Incontinence Pad bags 9.84 x 13.78inches Adult Diapers Disposable Bags for Adult Diapers,Incontinence Underwear and Personal Hygiene Products
