Kalak Water blotter - only heroic measures will save the pregnant woman

Description

Kalak Water Blotter
Kalak water was a carbonated beverage which had sodium carbonate added.  I found references online of the government refutiating their absurd medical claims of their product.  In fact, in 1919, the product was barred from a listing in the "New and Nonofficial Remedies" publication.  The claims on this blotter are really wonderful; this product is going to save the pregnant woman who might be in convulsions.  Meausres 3.5" x 6.  Unused.
Excellent condition.
Postal rates have recently increased yet again, and I am beginning to need to charge for shipping, which will be by 1st class mail in a plastic sleeve with rigid backing. If you would like any other shipping options, you need to contact me before paying for the item.   Payment includes required ebay tracking; and unfortunately I've had to raise my recent item prices a bit to accommodate the required tracking expense.   If you wish other postal services, you need to let me know before paying for the item.   In general, I have found the post office to be excellent.  But every once in a while items seem to take the long route to a customer's home.
I will always combine shipping, if I can, for items purchased at the same time.  If you have purchased multiple items, please wait for my note or corrected invoice before paying for the lots. The international postage shown is for Europe - please inquire if you live in Australia, the Far East or Africa.  Rates may be higher, especially if this is a heavier item.
Please be sure to contact me if you have any questions.
