What is the difference between a gold biostrap and a 3D biostrap?

The difference is that the Golden BioBand uses biomaterials, while the 3D BioBand uses tools that look like biomaterials. The Golden BioBelt is an absorbable biomaterial implanted into a woman's vagina to tighten the vaginal sphincter without cutting into the back wall of the vagina and separating the muscles. 3D BioBelt works by burying a rubber band under the skin inside the vagina, which is somewhat similar to a sack of drawstrings. It is similar to the drawstring of a sack, or like the cuffs of our clothes with an elastic band of that kind of feeling, the loose vagina to a certain degree of tightening, and also with a certain degree of elasticity.
