This Karen silver was purchased in Chiang Mai about 20 years ago when I was running a general goods store in Thailand. I sold everything at the time, but my wife kept these because she liked them. However, her tastes have changed and she no longer uses them, so I'm offering them to someone who wants them. Karen silver is originally very soft, and this bangle is very thin, so it deforms as shown in the second image when putting it on and taking it off. However, this is a characteristic of Karen silver, which has a high silver content. Although they look different in size, they are all 9.5 grams each, and there are 38 grams in total for the set of four.
