...call them what you like, the idea is ingenious and so simple.

Use the metal spring to slip over the existing button, the new collar or button extender is now held securely and sits beside the old one to increase the size of the garment fit by that increase in the distance between them.

We do not offer replacement for failure, as
 each Collar Extender has been individually tested by hand prior to dispatch.

They are designed to give a relaxed fit with the spring, approx 1/2 shirt size...and are not intended to provide a fully Elasticated extension. If they are subjected to unreasonable force, the spring will fail.
