Found and got some of these products (rubber bands) and budding ties from Germany. They may have agents in the US ....

they are very practical. (office type rubber bands, for me, lack the correct elasticity)...some guys also cut bands from used tyre tubes.
btw, saw first reference to these products on a very interesting small book dealing with grafting and budding written by Peter Klock.
Believe this book to be an ideal reference for beginners in the art of grafting/budding
The time to start budding figs in the Mediterranean starts by now...
