Glass Marbles (GL1)

Hello, if neighbours have any that are no longer played with, I'm looking for marbles. I have a glass jar I use as a plant pot holder, and it's around 1/3 full of marbles, it needs to be around 2/3rds full to better support my plant. (Photo included, looks better with natural light coming in the window, but it's winter and dark, her)

Marbles, or those glass blobs you use as spare game counters, glass beads, bigger bits of sea glass, anything small, colourful and glass would be marvellous please.
