Magic Cold-Activated Design — Custom Logo 550ml High Borosilicate Cold Brew Cup‌
This premium large-capacity cold change glass cup instantly shifts its color when you pour in iced drinks, making every sip a fun, eye-catching experience. It’s fully customizable with your own logo, perfect for personal use or as a standout branded gift.
✅ Top-Tier High Borosilicate Quality
Made of thickened food-grade high borosilicate glass, it’s far more heat and shock resistant than regular glass. It won’t crack when you switch between iced cold water and warm drinks, and leaves zero weird aftertaste to keep your beverages pure and fresh.
✅ Fun Cold-Triggered Color Changing Effect
The special temperature-sensitive coating stays clear at room temperature, and blooms into vibrant custom patterns the second you add cold drinks below 15℃. The color shift is smooth, durable and won’t peel off after hundreds of washes.
✅ Full Custom Logo Support
We accept custom printed logos, brand names, event slogans or unique patterns. It’s ideal for corporate giveaways, wedding souvenirs, team building gifts, café merchandise and small business promotional items to leave a deep impression on every recipient.
✅ 550ml Large Capacity With Full Set
The extra-large 550ml size holds enough cold brew coffee, iced tea, fruit infused water or smoothie to keep you hydrated for hours. It comes with a leak-proof BPA-free lid and a matching food-grade silicone straw, perfect for home, office, gym, picnic and outdoor use.
