AG45 Silver Rods good for bottle cage bosses etc...?

Hi all

I was looking to buy some more silver rods, had been using my friends who bought them from ceeway previously. as I usually buy everything second hand online I thought it might be worth checking and found these

AG45 they are called. I had asked my local senior framebuilder and he said he never really had any problems with any rods with above 40% silver…but i coulnd’t ask him about these ones specifically (he’s a verry busy man)
What do y’all say? they are roughly 3€ / piece instead of 7€-ish if you buy them from a shop…
thank you kindly :slight_smile:
