To avoid having a poo smell in your car? Seems like a good seal would alleviate the need for the magnet. But who knows.
low dog poop IQ
Japanese people don't wear shoes in their homes, they def don't put crap in their cars, good seal or not.
exactly. but get this... they take the dog poop inside and flush it down the toilet
Is the donpac+ really much better than the donpac????
I think it's size. the plus holds a 600cc whopper
Pro-tip: throw the poop bag away before you get to your car 
there are basically no public trash bins anywhere.* except inside convenience stores and nobody would be so inconsiderate to the beloved 7eleven employees.
you are expected to take your trash home with you.
they actually make cute little handbags specifically for holding your dog poop filled bags as you are walking your dog so innocent people aren't grossed out by seeing your poop filled dog bag. every Japanese dog walker has one.
get this other invention: our Japanese dog poop bags have 3 layers: first is like flushable toilet paper in direct contact with the poop, second is a normal plastic poop bag and third is like a mini plastic grocery bag with handles/ties.
you pick up the poop with the whole deal, twist shut the plastic poop bag, and carry that in the mini bag with handles (if you don't have a poop purse). when you get home, you open the poop bag, dump the poop paper into the toilet and flush it, then you can put the poop bag into the handle bag and tie it shut for an airtight seal and throw it in your home plastics trash.
*I know you mean just chucking it into the woods American style
