2. Cosplay Book - Consider getting him a book that focuses on cosplaying tips and tricks, or one that showcases different types of cosplay costumes and characters.

3. Cosplay Prop - If your grandson already has a favorite cosplay costume, you could consider getting him a prop to go along with it.

4. Cosplay Wig - A new, high-quality cosplay wig can make any cosplay costume come to life, and your grandson would love it.

5. Convention Tickets - If your grandson is a die-hard cosplayer, he'll surely love tickets to his favorite convention or cosplay event.
