I bought a bag of mixed beads from a shop I've used before and mostly they are great, some small discs broken in the post but mostly great quality. But annoyingly today I went to use some large beads that came in the bag in a new design. I planned it out, shifted around the colour, invested in it and then when I got half way through stringing I found that two large beads were not drilled all the way through, how annoying. I don't have any more glass beads large enough to replace them and the trick of poking wire through the drill line isn't working so I was wondering if anyone knows a shop I can buy something similar without buying a whole bag of mixed beads.
I've put some pictures below so you can see what I'm looking for (and couldn't resist shoing what I'm working on).
This is the bead (glass):
