Fast delivery， these corner protectors come with 10pcs round and 10pcs square angle shape protectors. I bought this to put in my work place kitchen area，where there are too many stainless steel shelves or dangerous corner maybe to accidently hurts somebody. These protector very useful and easy to fits . The stickers in the protectors are strong enough. Due to need it long lasting，I myself put some super glue to make it really stick in every corner. Highly recommended.
