Frequently Asked Questions

Where is my order?

Check your shipping confirmation email for your tracking number, then visit our order tracking page. Orders typically arrive within 5–15 business days after a 1–3 day processing period.

How do I return an item?

Email us at support@jcfyoo.com within 30 days of delivery. Include your order number and reason for return. We'll send return instructions. Items must be unused and in original packaging.

Are batteries included with my order?

No — batteries are not included. Battery versions require 3×AA alkaline batteries. USB versions plug directly into any phone charger, laptop, or power bank.

What is the difference between battery and USB string lights?

Battery lights run on 3×AA batteries — great for areas without a nearby outlet, like mantels, shelves, or outdoor patios. USB lights plug into any USB-A port and stay on as long as they're connected, making them ideal for desks, bedrooms, and permanent displays. Browse our battery lights and USB lights to compare.
