HOWEVER they came with two holes :( one small in the front and a bigger one in the back. When I put them in, they seem squished. Its small size and very compact, good for traveling. I have vinyl siding and hang some house ornaments (metal butterflies) and I have tried the extra strong Velcro by 3m. This did NOT come with the mounting hardware as they described. First wash turn them inside out to avoid black fuzzies between your toes. But the last couple of years the sizing is different. Can?t beat the price though. They arrived and I went to slip on these bad boys and I immediately regretted it. This is my 3rd pair of Rowkin buds.
