NALACAL Metal Fidget Slider - Magnetic Brick Fidget Toy EDC Fidget Toys for Adults, ADHD Anxiety Stress Relief Toys, Ideal Gifts for Father Man & Friends

This is really one of the best ones out there, strong magnets, great feel, pin point sound and overall you won’t be able to put it down. But…the outer shell material corrodes in less than two months, and it will leave reside on your fingers and hands, and give off a weird metallic smell.I reached out to the seller, but their reply was far from ideal, “We are sorry to bring you a bad shopping experience. Our products have been safety tested and do not contain any life-threatening chemicals. Please try to avoid them getting exposed to water”,So I sent back a few photos of the corrosion and threw the item away, as I don’t feel comfortable with chemical residue all over my hands (especially the non-life-threatening ones).Just before I threw it out,I decided to open it up and see if I could at least save the magnets (as they really were good, and surprise surprise they were all rusty and corroded, cracking and even discolored, and with a powder (which is similar to that of an expired battery), I guess the product safety check was on a break.Anyway, very unfortunate, and a shame.
