For sale is a 2-box set of handmade vintage pine wood trash bag dispensers.  The large one measures 11 X 7 X 7" on the outside and 9 1/2 X 5 1/2 X 5 1/2" on the inside.  The small one 8 1/2 X 5 X 4 3/4" on the outside and 7 X 3 1/2 X 3 1/2" on the inside.  Each lid extends into the box a little less than 1/4" so you you will lose that much in capacity.  I don't know if there is any kind of standard roll size for garbage bags.  In the photo you can see my disheveled partial roll of tall kitchen size bags in the larger box.  The condition is good for the age.  The lids fit imperfectly.  There are dents, scratches scrapes on both boxes but do nothing but add to the personality of the pair.
