Tollyboy was originally foundered in 1956 on two guiding principles.
"Quality and security"
"Simplify and add lightness." J.H. Higginbottom 1956
To this day we still stand by those principles.
Tollyboy products are made to measure and should fit almost like a second skin.
Tollyboy products are non adjustable because like any made to measure item they are intended to exactly fit the wearer and no one else. They are designed for serious long term use to ensure chastity, not just for the BDSM scene. In BDSM play belts are typically worn for hours to days. Tollyboy belts can be and have been worn continuously for months - years. (Many belts are of course used for BDSM but it is not their only intended purpose.)
To make Tollyboy items adjustable would break our founding principles in the following ways.
Adds complexity leading to more potential points of failure.

Many Tollyboy products are copied, but none equal our quality.
