Gift ideas for a friend of a friend?

Hi, r/hookah!

Forgive me if this kind of post is not allowed here. A birthday for a friend of a friend is coming up and he's recently gotten into hookah, so I thought I'd get him something related to that. Since I know little on the subject, I figured I'd ask you guys -- if you could be gifted a hookah-related product, what would you want?

Details:

• He's only been in the "scene" for about 3 months, but I think he's learned the concepts fairly quickly. The last time I talked he said he was digging fumari mint and starbuzz apple.
• I have a budget of around $30 or less.
• His birthday is on the 23rd. He's long distance so I figure I should ship by the 15th or 16th.

Many thanks! Have a great night. :)
