## Features

- FINISH CORNERS - Add the perfect finishing touch with the NEW InstaTrim Corner & End Caps! These innovative corners close the gaps of 90-degree inside and outside corners to create a clean, finished look. Great for windows, counters, flooring, and more, these trim pieces cover the corner gap between two pieces of InstaTrim flexible trim.
- EASY APPLICATION - Don't waste another afternoon on a frustrating DIY project with confusing instructions. InstaTrim has easy-to-follow, clear instructions that will make your next home improvement project a breeze. These corner and end pieces work perfectly with InstaTrim 3/4" flexible adhesive trim. Simply slide the ends of the InstaTrim strips between the “face” and the “tail” of the cap piece at the corner - that's it! Then, sit back and enjoy the professional, finished look.
- NO MESS, NO STRESS - Traditional caulking can be messy, even for people who have used the product before. InstaTrim caulk tape takes the mess and hassle out of caulking projects, while still providing great results.
