I got them, very wide, they are the kind used for granitas and you can suck up ice fragments, I left them in water for a day and the next day, by scrubbing them with the green side of the sponge, they peeled and color came off both top and bottom. The sponge had to be thrown away, it was full of color, and I wouldn't dare use them with anything hot so I don't drink color. I usually put French coffee in a thermal glass and drink with a straw.

In short, if the ones that haven't lost their color don't lose it, 3 of them are metallic after washing. The red, the light blue, and the pink ecru. If all lose their color and if all are painted with the same technique, which from the texture of the color it seems that the 3 are of poor quality and painting technique with a rough surface, then they are not worth buying. I think they put low-quality colored straws together with acceptable quality ones.

Made in China like many products.
