Have had dogs all my adult life and have used poop bags way before it was cool. So yes, I know what makes a good one. These are large enough for my 100# GSD mutt, lightly (IOW not offensive) scented but enough to "cover up", and, also importantly, the bags are biodegradable with a cardboard (!) center roll to wind bags on. Duhhhh. But they thought of this - most don't. Extra points for that! Bags are not so thin either that they break, which truly matters, right? Go get these in quantity to reduce packaging and save $. Not a risk, trust me. BTW I have not received anything whatsoever, no discount either, for this review (tho I wouldn't refuse anything that may be passed my way...ahem.) Recommend.
