And I have used a hot glue gun before, but with gems that are very tiny, I dred the mess. But also I need a sort of glue that is strong but would work with a cheaply plastic case. Thanks for any input.
Consider using e6000 which is a very strong adhesive for multiple surfaces like plastic or metal. You can apply using a toothpick to control exposure. Many craft stores carry this or purchase at amazon.com.
Hope this helps
