Ring Size Card
(Add-On) Free with purchase


Use this Ring Size Card from A KIND OOOF to measure your ring size. Your ring should fit your finger comfortably; snug enough so that it will not fall out, but loose enough to slide over your knuckle. For best results, measure your finger size at the end of the day and when your fingers are warm (fingers are smaller in the early morning and when cold).

1. Relax your fingers when measuring.
2. Slowly rotate the card towards your finger to find the right fit, snug enough so that it will not fall out.
3. If the ring size is too big, the card will feel loose and rotate easily on your finger.
4. The Ring Size Card is made of paper and tends to expand a little while using it.
5. The measurement results are only for reference. For a 100% fit, you can purchase our Ring Sizer.

• Ring Size Card will be included with every purchase (DO NOT add to cart).
• You can request online for a Ring Size Card without any purchase and we will post it to you with a postage fee of S$0.50.
(available for Singapore only)

To maintain the beauty of your jewellery, please remove them when you shower or going for a swim in a pool or to the beach. And also, to avoid perfume or makeup where they might come into direct contact with your jewellery. Keep them dry at all time.

Proper care is the key. As a general rule, your jewellery should always be the last thing you put on before going out and the first thing you take off when you reach home.


• Note that the circumference and diameter measurements match the inside edge of the ring.
• A KIND OOOF uses SG/CN/JP for ring sizes.

How to choose the jewellery material that suits you?
Will I be allergic?
Will the colour fade?

925 Sterling Silver
925 Sterling Silver consists of 92.5% of pure silver mixed with 7.5% of other metals (often copper, nickel or zinc) to create a more durable metal. This is different from silver plated jewellery, where a thin layer of silver is deposited over another base metal or alloy. When 925 Sterling Silver starts to oxidise, just wipe with a silver polishing cloth to restore shine. Most people do not have allergy reactions to 925 sterling silver.

Due to the softness of brass properties, brass jewellery are almost always plated, and the plating process increases endurance and durability, and makes the surface smooth and beautiful. It is normal for oxidation and discolouration to occur when the jewellery is worn for a prolonged period of time, and is in contact with body sweat. Alternate the wear of your jewellery pieces, and store them in zipper bags to reduce discolouration and extend the lifespan of these precious trinkets.

Stainless Steel
Stainless steel is a lasting metal for jewellery. It is also hypoallergenic, excellent for individuals with allergies and sensitive skin. Stainless steel jewellery are long lasting, and its colour will not fade easily.

Plating Process
Gold plating is a method of depositing a thin layer of gold onto a base metal such as Silver or Brass using an electrochemical process. It is a rich and highly polished material that is perfect for jewellery or precious objects. The gold plating process gives the jewellery a smooth and beautiful finish, and also makes the surface durable and strong.

Rhodium Plated Jewellery
Rhodium is one of the rarest and most valuable precious metals. It is often used to plate jewellery because of its highly-reflective finish. It is also hypoallergenic.

Everyone's physique is different, and allergies are likely to be different as well. By understanding more of the above materials, you can pick the right jewellery that suits you most.



如何挑選適合自己的首飾材質? 會不會過敏? 會不會退色?

925銀是指含銀量達92.5%,國際上的標準純銀,千分之925的銀加入剩下千分之75的合金(常見的有銅,鋼),使925純銀較硬有韌性。( 這與鍍銀首飾有很大不同,鍍銀首飾上有一層薄薄的銀沉積在另一種賤金屬或合金上 )925純銀氧化後只要擦拭可恢復光澤,大多數人都不會對925純銀過敏
