All orders made via THREEONETWOFIVE online store will be packed in a cotton pouch and cardboard box to protect the jewellery during shipment.

For gifting, we can give you a card for you to handwrite your message for the recipient or we can handwrite for you too! Simply leave your message on the "Note" section upon checkout.

When you have received your order:

Reuse the paper box as many times as you can before you recycle it. Use it to store not-in-use cables, batteries, stationeries etc. Some of our customers have used it to store their accessories when traveling! 

Reuse the cotton pouch for your mini toiletries, makeup, first aids etc. I personally use them to store my earphones.

Always consider reusing before you send them away for recycling! 👍


Frequently Asked Questions

  • Can I do without the box?

Unfortunately we had some bad experiences when we shipped without the box. Earring posts gets bent or detached. We really don't know what happens during delivery. We have to ship your order in the box to prevent damage and as a way to make your parcel more "obvious" so that it will not be overlooked in the delivery warehouse. Alternatively, you can select "Self Collect" option to save on packaging! 

  • Can I get more cotton pouches?

We limit one cotton pouch to one order. If you need more, you can purchase them here.


Thank you for your understanding! 😊 Please let us know how we can do better too, via Instagram or you can email to




Handmade with good intentions. As natural materials are used, do expect some slight irregularities, making the piece you own one of a kind.

Frequently Asked Questions

  • How do I care for my jewellery?

    Most of our pieces are made with sterling silver and stainless steel. Under humid conditions, even precious metals like sterling silver will oxidise overtime. Wipe jewellery with polishing cloth provided. (Free with any purchase of sterling silver items!)

    For stainless steel products, just wipe the jewellery clean — removing any dirt and debris — before you store them in your jewellery container.

    For more useful information, you can read our detailed blog post on the materials we used for your jewellery here.

    A little care goes a long way.

  • How do I measure my ring size?

    We recommend that you measure the circumference (i.e around your finger) rather than diameter for more accurate measurements. You can also find a ring size guide along with instructions how to measure your ring size under every ring listing.

    Alternatively, we recommend using our adjustable ring sizer. (It's free of charge!)

  • How long will my order take?

    We ship ready stock items within 1-3 business days. For made to order items such as custom signet rings, it takes 4-5 weeks at least.


    Singapore: 1-3 business days

    Southeast Asia: 5-7 business days

    Rest of the World: 7-14 business days
