Good but no info

I bought these popsicle forms, and am reasonably happy with them. They work just as photoshoped. HOWEVER, There was no indication thatthere are 8 forms in the box. The picture shows only 4, so I was happily surprised to find more. Although I bought 2 boxes, Because I wanted 8. So now I have an extra-box to give away ... Additionallly, There Is No indication of the kind of plastic of Which They are composed, nor is there any indication of Whether They Can go in the dishwasher or not (I am washing them by hand to be on the safe side). In fact, there is no textual information via Amazon nor in the packaging at all. (Through my first sorbet-making experience now with thesis forms, They hold about 3/4 liter.) So, hummm ... Style good, very information poor.
