Scottsdale Mint bars, are one of the best. I have stopped stacking bars, but if I did, it would be the SM stackables that I'd get. It truly lends to better stacking in storage. I am now seeing the inconvenience of odd-shaped bars for basic stacking. I'd even just stick with the 1 oz generic bars, they are so much easier to handle, for me personally. Have a wonderful week, bestie. Take care.
