I intercepted this small object inside an envelope mailed to my teenage child. (I am sure many have a strong opinion about my behavior, but I just want to know if this thing is harmful or safe.) It has some electronic or electrical features that prompt me to post this question here.
It is a small plastic strip, 2cm long. Round holes along one long edge. Little windows along the other edge. Appears to be a very tiny electrical circuit chip inside each window. On the back of the strip, there is a little blister behind each window. Each blister has a little round hole revealing a blue green surface behind it.
Thank you in advance for taking the time to offer any opinions.
