    Great product. Cheap price.

    I always order my silicone from here because it's a lot less $ than home improvement stores, but it's still a great product.

    Great silicone

    This silicone was just what I was looking for! I needed 100% silicone sealant that is slightly thinner than typical off the shelf silicone and this was perfect!!!
