Forgive me as I am new to this forum, I have recently purchased a pill box and it has the following marks:
Square with WH in it, A upright rectangle with some symbol but not very clear and a third square with 90 in it. Looking at your library images it is leading me to believe the could be chinese export. I bought because it is pretty but when I buy something I like to try and find out about it. I will apply images but I don't want to waste anyones time. Please let me know if you think you can help.
