Gold
Gold is resistant to oxidation and discoloration, making it a material that retains its shine for a long time. However, oil from skin or cosmetics can cloud the surface and dull its brilliance.
— Daily Care
After use, gently wipe with a soft cloth (such as chamois leather) to remove oils before storing. This simple step will keep it looking beautiful.
— Deep Cleaning
If you notice dullness or dirt, dissolve a small amount of mild detergent in lukewarm water and wash gently. For intricate details, using a soft brush (like a toothbrush) can help clean them effectively.
After washing, rinse thoroughly with fresh water, wipe off moisture with a soft cloth, and let it dry completely.
Pink Gold
Since pink gold contains a higher amount of copper, it may discolor in response to sweat or hot spring components, similar to brass or silver.
Hot Springs & Pools
Even with K18 gold products, the alloy metals mixed for strength can react and cause discoloration. Please avoid wearing your jewelry in hot springs or pools.
Silver
— Sterling Silver (Silver 925), Pure Silver (Silver 999.9)
The biggest enemy of silver accessories is blackening caused by "sulfurization." They discolor by reacting with sulfur in sweat or the air.
— Preventing Discoloration and Deformation
Avoid wearing while bathing (especially in hot springs or with sulfur-based bath salts!), playing sports, or doing housework.
Perfume and hairspray can also cause discoloration.
Avoid storing in direct sunlight or high-humidity areas (such as bathrooms).
— Daily Care
Gently wipe with a jewelry cloth after removing.
If you have applied sunscreen or hand cream, or if the surface feels sticky, wash gently with a mild detergent (hand soap is fine) and let it dry completely.
(Note: Some natural stones are sensitive to detergents. Be careful not to get detergent on parts other than the metal.)
— If Tarnish Occurs
You can restore it to a near-original state using commercially available metal polish with abrasives.
Household items like vinegar or baking soda can also restore shine, but they may cause scratches or discoloration, so we recommend testing on an inconspicuous area first.
Please refer to the "Care by Finish Type" section below for cleaning methods based on the finish.
Caution: Do not polish oxidized (blackened) areas. Using vinegar or abrasives may fade the finish.
Caution: Do not use abrasives on natural stones.
Brass
Brass changes to a deep, antique gold color as you use it. Since it is sensitive to moisture and salt, "verdigris" (green rust) may occur. After use, gently wipe off sebum and dirt with a soft cloth and store in a well-ventilated place.

Pet ID Tag Care & Precautions
For basic cleaning and polishing of ID tags, please refer to the care instructions for each material (Brass/Silver) above.
However, since pets often wear them constantly, please note the following points as the environment differs from human jewelry.
— Dirt & Verdigris from Constant Wear
Constant wear makes tags prone to sebum and mud accumulation. Please wipe off dirt frequently to keep them clean.
Brass & Silver 925:
If moisture or dirt remains, copper components may react and cause "verdigris" (green rust). Please check carefully to prevent color transfer to light-colored fur.
Pure Silver (Silver 999.9):
Since it contains no copper, verdigris will not occur, but dirt can still accumulate. Please clean regularly to maintain hygiene.
— Hardware Wear Check (Safety Inspection)
When cleaning, always check the condition of the hardware (jump rings, etc.).
Any metal will gradually wear down due to daily movement and friction. Regularly check if the metal has thinned or if gaps have opened, and replace the hardware if wear is observed.
— Cleaning Engraved Parts
If dirt accumulates in the grooves of deep engravings, use a soft toothbrush to gently scrub it out.
If using detergent, rinse thoroughly to prevent skin irritation and ensure it is completely dry before putting it back on your pet.
