iDesign™ Series Cork Frameless Bulletin Board, with Band, 3 sizes.

I also bought these at 50% off and would say they are not worth it. The cork is much thinner than a standard thumbtack --maybe ~25% of the thumbtack length. They've backed them with something else which is much harder to push into and also makes them much heavier than if they were more cork. Disappointed.

Not worth the full price, but the 50% discount made it reasonable. The actual thickness of the cork is very thin, but adhered to a thicker frame.
