What is a watch without a strap? It's basically useless.
So, no matter if you enjoy making or repairing watches as a hobby or you do it professionally, at some point you will find the need to use the strap link pins.
With these sets, of different quantities of quality stainless steel bars with double flange, you will have your needs met for a long time, and for many different models of watches and widths of bands. And they come in a labeled, transparent plastic box for keeping the 18 different sizes separated and easy to access.
We have to prepare each shipment individually as they are ordered, so allow it in 3-4 weeks to arrive in the USA/Canada (to be safe) and 3-6 weeks rest of the world, though they are usually delivered much faster.
