These have strands of glass in them. These will ward off the witches and their spells though we definitely haven't tested each one. Made in China, these are about 4 inches across. Combine these with all of our other glass balls for the pricebreak. There's about a 5mm rough hole near the top of the ball where presumably little hands reached into the ball to assemble the tree. We can fit 6 in a regional postal flat rate box. It costs about $65 to ship a case to Quebec from Vermont via UPS. Clickclick here to visit our page of witch balls, gazing balls, hanging hearts, etc.
