Car Cup Holder Expander — Universal Insert for Large Bottles & Travel Mugs

Finally fits your water bottle. No more balancing acts, no more spills.

Standard car cup holders are built for one-size cups that nobody actually uses. This adjustable expander inserts into your existing cup holder and expands to grip any size bottle, tumbler, or travel mug from 2.5" to 3.8" in diameter — securely, without wobbling.

• Fits virtually any container — expands from 2.5" to 3.8" diameter, works with all large tumblers
• Spring-loaded grip — holds bottles firmly on bumpy roads and hard stops
• Swivel base — rotates 360° so you can grab your drink at any angle
• Non-slip silicone lining — protects bottles from scratches
• Bonus tray on top — holds your phone, coins, or snacks in a secondary dish

Works with your Hydro Flask, Stanley, YETI, Nalgene, and any standard tumbler. Setup takes 5 seconds.

Universal fit for most car and SUV cup holders. Available in black.
