We have noticed that some of the stitching/edging on some of our calendars isn't straight, so some pockets may be slightly smaller/larger then others. Because of this we are discounting all the calendars and selling them as seconds with known faults. Once you fill them with treats it won't be noticeable and the issue is not on all calendars. Because we are selling them as discounted seconds they are on final sale and not eligible for refund or return.
