13 Sets Moving Box Glasses Divider Kits Cardboard dividers fit boxes about 16 x 12 x 12 inches for Kitchen Dish Packing Wine Glassware Cardboard Box Compartments Dividers (Box Not Included)

The instructions specify the size of the box these fit in, and Lowe's sells them. They fit perfectly in the box. I used bubble wrap for my good crystal, and nothing broke during an interim and final move. I then reused them for transporting beverages, canning jars - anything that had breakage potential - and they held up through at least four moves per box. Well worth the cost.

I loved these, and they go great with the Lowe's boxes like other reviews mentioned!

They were the prefect size for what we needed

Work like a charm for packing wedding glass candle cylinders! I could fit 12 per box with the dividers!

I found these to be the best deal on Amazon. You seem to get a lot for the money. These fit perfect in a Lowe’s small moving box (16 x 12 x 12).

I have a number of 16 x 12 boxes that I wanted to use for fragile items (not stemware in my case--mostly decor items). The dividers fit snugly but without bending. Some items were packed in paper and some in polyurethane, and in each case the individual compartments held their shape against the pressure of the packing. I appreciate the additional structural integrity the dividers provide for the boxes, so the boxes can be lightly stacked as needed. Saved me a little money over buying specialty storage, too.

The dividers seemed to be ok but did not include the box or correct box sizing instruction. Ended up throwing these away because it did not work with the boxes I had. What a waste

The media could not be loaded. Got these inserts for my glass-wear and just added them to a regular box that these fit directly into. A whole lot cheaper doing it this way, getting the inserts separately from the box and then buying the right size box. My glasses fit perfectly in them including my long stem wear. Easy to assemble and hold up nicely once assembled and in their box. Love the protection that these give that is more than just wrapping them in paper.
