I think most of the ones you can get now are forever stamps. It just means that they are good for basic first class mail regardless of what the rate is when you use them. So instead of having to get one or two cent stamps when the rate goes from 48 cents to 50 cents, if you bought them when they were 48 cents, they’re still good now that the rate is 50 cents.

They also are not valid for foreign mail; domestic use only
