Final answer:
You can write an email to your friend Toni informing him about the skateboard and your willingness to give it to him.
Step-by-step explanation:
Hi Toni,
I hope you're doing well. I wanted to let you know that I have a skateboard that I don't use anymore and you mentioned that you're interested in having one. If you're still interested, let me know and we can figure out a time for you to pick it up.
Thanks, and take care!
Best regards,
Your Name
