Review: Easy Install - our corners looks amazing ! great value. perfect for a garage. Easy install
Review: PERFECT SOLUTION, PERFECT FIT - THESE WERE FANTASTIC!! Moved into a 50+ year old building ... bathroom toe kicks were a MESS ... someone had used a rotating floor cleaner of some kind and chewed them up horribly! These in/out edges were the perfect finish to cap 4" rubber strips which otherwise would not have a "finished" look. We used Henry Ready Set Mastic (from desertcart!) which filled in the "chewed" spaces in the toe kick and gave a super seal for the moldings and edges. QUICK, CLEAN & PERFECT SOLUTION!!

### ⭐⭐⭐⭐ Adhesive slightly lacking.
*by P***A on July 29, 2024*

Definitely completes the look of vinyl wall base application. Adhesive a bit lacking on a few but remedied with adhesive on hand. I do wish one could buy in/out corners separately and as many as needed. Could have used one more ("inny") but, alas.
