The inserts that come with our cup holders are very cost effective, but are not always ideal for certain drinks. The step down design can be a very nice feature sometimes, but sometimes it can be a hinderance. For example, most 20oz tumblers are a in between size and will not set flat, so they get tippy and spill. So we now offer a replacement insert that is the same size all the way down.
Please note: This insert will only fit the larger cup holder, NOT the smaller top insert.
