Flowers are the main gifts for Teacher's Day, but crystal ornaments are better, especially for your grandpa, who will be very happy. You can also customize a crystal carved table with photos of your grandpa and grandma, which is a very creative gift. You can also give some strange gadgets to your grandpa.
