What sized box to pick under flat rate shipping on USPS site?

[MBL Racing]

The boxes that I use and I assume all of us use are the 8 3/4 X 4 1/2 X 2 which isn't listed on the USPS Flat Rate list. The closest is a 5 3/8 X 8 5/8 X 1 5/8. These are pretty close but I just wanted to hear from someone that has used this before and can verify this will work.
Thanks,
Mark

I use my own box and just enter the dimensions. I use DD4H boxes and then put them in another box with about two inches of soft faom around each individual box that way my cars are double padded. I fit it all nice and tight too. I don't want anything inside moving around.

Depending on how many cars you are sending. I am sending 5 cars so I used a large flate rate box. Don't know if this helps.

Thanks Kinser.. I already printed a couple labels using the small flat rate box listed. How long does one have to get a refund?

Ok applied for refund and will redo under use my own box.

I've never done a refund. I think it was bclinn in another thread that said you can only do it same day.

That's a good idea AC. Do you use the DD4H boxes inside the big box or just use foam with cut outs for each car?

No I'm using the 4" wide box from John with the closed cell foam inside. It's about 2" thick I think . The 1 5/8" was the smallest choice the flat rate drop down window was giving on the USPS website.

I have all 5 cars in the legend boxes fom John inside the large flat rate plus top and bottom and all 4 sides are lined with pillow foam. It all fit the Large flat rate box
