Now you can reduce triangular canes with no cave-in and without distortion. Thank goodness!
For years, I had no lids on my Pringles, no tops on my Planters. I took them all and cut them up to make end caps for my canes. Worse yet, I didn't like scraping the clay off of them; so I needed A LOT of lids. Then, one fine day, I decided to find someone to make me some CaneCaps. They are sturdy Lucite disks in just the right sizes and shapes and the clay wipes right off.
You can reduce your canes very quickly with the ends perfectly intact. (And, yes, now all my snacks stay fresh.) Triangle CaneCaps come in three sizes. There are 6 in a set.
Loosen one edge of the protective paper with your fingernail or blade and it peels right off.
