I am looking for a web site that sells the tenyo milk tumbler. if anyone knows of a web site please let me know. thanks and God bless.

Did you find the milk tumbler you were seeking? If so, I have one, with instructions from Tannen for the Wonder Glass, issued years ago. Don

Tenyo stopped supplies to the U.S. a while ago.
They will re-release it again but with Japanese packaging and English instructions.
Don't know when but soon. I don't know the product they plan on releasing though.
Unless you are collecting it there are plenty of substitutes out there for it.
If you do collect and need a Telesphere or Oh no I have them brand new in the package. Hope this helped!!
