Magnets don't stick to them

Since magnets do not stick to these straws, I'm going to assume that these are made from aluminum and NOT stainless steel. I'm sure they work like regular straws and the brush works well too. Length is good, but I took off 2 stars due to the inaccurate material reporting. If you are someone who wants/needs to avoid aluminum by using stainless steel, buyer beware. And keep a few magnets around to double check your purchases!
