I love these! They are not sharp, they work perfect for small snacks and oils. Great price! Shipping was so quick! I will definitely be purchasing again! Thank you!

Wonderful shell shop

First time customer ordering shells. I didn’t know what I needed and the owner was so kind and helpful to me. Wonderful customer service in helping with sizing. She went above and beyond to get me what I needed. The shells were packaged with care and love. Each item was individually wrapped and some were even wrapped in bubble wrap where the bubbles were shaped as hearts. I’ve never seen such a thing and it was a nice touch being so close to Valentines Day. Everything was in perfect condition, no chips or cracks. The quality of customer care is top notch. I will definitely be placing another order in the near future.
