Pros : Love the small size of the beads. Mold is compact and can fit into a relatively small kiln. Don't need alot of glass to make the beads.
Cons : Can be difficult to coat the posts of the mold. I suggest using an extra coat of MR-97 to make sure you've coated the posts completely. Directions for the amount of glass given in grams. Wish a measurement cup in grams was included or available for purchase.
Other Thoughts : Overall, I like the mold. The first time I used it one of the square beads stuck at the post. I was able to pop it out with a small tool but the post popped out with it. The rest of the mold is still usable. Despite this, I like the mold and would recommend others to buy it if you want to make small fused glass rings.
