This is a large glass paperweight by Norcrest Japan. It is 3" in diameter and stands 2 1/2" tall. It has blue Millefiori flowers and glass bubbles can be seen as well. It has one maker's mark at the top that looks like a line halfway down the top. It pretty much goes unnoticed. The Norcrest sticker is on the bottom. It is in wonderful vintage condition.
