These small peelers with short handles come in brightly colored plastic and peel better than any others I’ve tried.
It will cost you less than five dollars. It will peel effortlessly. It ain't complicated, it just works. For some reason, I always have trouble removing the skin from Champagne mangoes. I do the knife cut around the longest circumference and then pull the skin off technique usually, but due to the thinness of the skin, I always end up swearing. I think once a long time ago I tried using a regular peeler to peel mangoes and it ended badly. I've also tried the cutting off the two side pieces and then cubing and popping pieces out. Nope. This peeler can peel champagne mangoes. Happiness.
