Talk about a timesaver! Using these metal, beveled support pins is far easier than the tedium of cross wiring your foundation for support. In fact, it's the only support system we recommend. Similar to tiny clothespins, they add strength and support to your beeswax foundation. Simply press the metal pins through the holes in our wooden frames, so the foundation is nestled in the pin's slot. Simple, fast and effective! Note that support pins are included when you order foundation from Bee-Commerce. Get these if you need extras. About 200 Support Pins.
