Just the right pizzazz.

The knobs give just the right amount of pizzazz in my bathroom and kitchen. Love them.

Excellent quality & customer service!

I purchased 32 sand dollar knobs & 17 pulls (49 total) for my kitchen at my beach condo in CA. Every one of them arrived in perfect condition! They look absolutely stunning on my white cabinets! The silver/pewter like color is perfect with stainless steel appliances & the attention to detail is amazing! The people at Costello Coastal Knobs were very pleasant to work with and extremely responsive! I loved the knobs so much that I decided to order more to upgrade my bathrooms (sea shells) & a built in hutch (dolphins)! Again, they arrived quickly & in perfect condition! I had friends over during the Holidays & they could not stop raving about how awesome these knobs were! I would put this company & its products on the highly recommend list!!!

Shipped quickly!! They are beautifully crafted and designed!! Just what I was looking for

Plumeria Cabinet Knob - Small
Kathleen Paganelli

These drawer pulls are really beautiful! Perfect way to update our bathroom! Great service from company too! Would order again.

Perfect!!! Thank you!!!

Searching for the right hardware for my charcuterie board project I came across these. Great price, fast shipping and super customer service. Turned out incredible and the Sperm Whale handle pulls were of highest quality and incredible detail. Thank you so very much for a perfect customer experience!



Such high quality I am going to buy more for all kitchen cabinets.

Beautiful design

Such a great version of a dolphin. Of note the piece is a bit thin and can flex/bend towards the tail. Our cabinet installer noted this on two items we purchased (dolphin and palm tree). We have it in a guest bath that will not have much cabinet use. Super prompt delivery for all the pulls/knobs we ordered. Great service!

Exceptional and beautiful craftsmanship.

I recently purchased the small sea turtle knobs for my newly renovated masterbath. My order was promptly shipped and arrived quickly. I can hardly wait for the construction to be completely finished so they can be installed. The attention to detail, beauty, and craftsmanship is truly exceptional. I absolutely LOVE them! I also love that Peter’s name is stamped into the pewter on the backside. My poor memory won’t hinder my ability to order additional items in the future LOL!! If you haven’t taken the time to read Peter’s story, you should. It’s a beautiful history of how Peter became the artist that he is.

Excellent Choice

Excellent, choice the artist was referred by our custom cabinets maker and he was just right! The details on each piece are amazing. We are making another order.

Love the Dolphin Knobs

I have been ordering Peter Costello’s knobs since 2012 and I love them all, the quality and beauty is outstanding. You will never ever be disappointed. 👍

Sand dollar knobs

I purchased 2 for accent. They’re perfect for my setting. Only wish they came in polished chrome. I would buy more.

New cabinet knobs

I love them so much on the new pantry that my husband just built that I'm ordering 2 more. Nice workmanship.

Always Superb

My third order from Costello and once again I'm thrilled. They're great. You should really get some of these for your home. You won't be disappointed.

Great Workmanship

They are beautiful

Absolutely Fantastic!

My wife and I purchased the Mallard Head knobs for a kitchen re-model we're about to begin. Within an hour of their arrival, we placed another order - Scallops for our master bathroom, and Sand Dollars for our up-stairs bathroom. You've got to see these to fully appreciate their beauty and quality. We are very pleased, and we will definitely be ordering more stuff from Sea Life Cabinet Knobs. You should too!

Great knobs!

I love these! good price, great quality, quick shipping.

My beach house
