Welcome to the Embossing Die Company!!!
All of our stamps are Made in the U.S.A. (New York). The stamps come with a lifetime guarantee......if, at any time, you are unhappy with the impression they make, simply return the stamp and a new stamp will be sent to you. Therefore, you never have to worry about them "wearing out".
The stamps are made from a very hard plastic (a homo polymer resin), but since they ARE plastic, they cannot be used with heat (the melting point of the plastic is 350 degree Fahrenheit). They are NOT made from PLA (polylactic acid) which is hand wash only, cannot be exposed to direct sunlight, and cannot have prolonged exposure to moisture or hot water.
Here's a nice video review of the stamps:
