Since this product came out back in the 80's I've bought 2 sets. The First set I bought was when they were first marketed, and my husband and I used it til the velcro gave out 10+ years. Our second set is still going strong after about another 10 years. We will buy another set when(not if) that set perishes. Excellent for the price.
As the publication says-no metal so is not embarrasingly exposed in places like airports.
This is not the first time we have given our praise for this product, as we were quoted by the manufacturer in Bondage Life- Buyers Guide.
By the way, the Wrist and Ankle set has different sizes for the wrist and ankles, versus the basic bondage set has 4 the same size.
May all that buy this product enjoy it as much as we have.
