Will this fit into my factory cup holder without modification?

Yes. This insert slides directly into the OEM cup holder cavity. No cutting, drilling, or adhesive required — just drop it in and it's ready to use.

Can I remove and reinstall it later if needed?

Absolutely. The slip-in design means you can pull it out anytime and swap it back. No permanent installation required.

Does the rubber lining wear out over time?

The rubber is designed to handle repeated use, but like any wear item, heavy daily use will eventually show signs. Replacement inserts are available if you want a refresh down the road.
