The glass pieces used to create these are molded and thicker than the average flat glass marble. They are 1 1/2" across and the thickness varies a little with each piece, but is generally around 1/2". Magnets are heavy duty ceramic and will hold several sheets of paper.
All magnets pictured on the right are available for purchase. If you see one that I have not listed, please convo me and I will make a listing for it ASAP!
I am very convo friendly, so please contact me if you have any questions about the process.
