Twelve Houses Resin Jewelry FAQs

Is resin jewelry safe to wear? 

We use ArtResin in our jewelry, charms and accessories.   This resin is a non-hazardous material that has been extensively tested for safety.  It has no fumes and gives off no VOCs, even in its liquid form.  It conforms to ASTM D4236.  After curing, it can even be used as a food contact surface.  All items we sell are correctly cured.  So yes, our resin jewelry is safe to wear!!

How do I take care of my resin jewelry and charms?

To clean, use a mild soap and dry with a soft cloth.  Don't use any abrasive cleaning material as it can make micro-scratches in the resin surface.  

What do you charge for shipping?

Twelve Houses has a flat rate shipping charge in the US of $3.   If your order totals over $50 (excluding tax and shipping), you’ve earned Free Shipping!!  For international orders, we find the best rate for you, and charge you that!  You'll never see a handling fee on a Twelve Houses order!

Do you offer gift wrapping?

All of our products arrive in a pretty fabric bag, suitable for gifting!

I'm allergic to nickel.  Can I wear your ear gauges (plugs)?  Yes, there is no known allergic cross-reactivity between any metals and epoxy resin.

Can someone be allergic to resin jewelry?

Yes, but it is relatively uncommon.  Resin allergy occurs mostly in people with occupational exposure to resins such as boat-builders. If resin allergy occurs, it is usually a contact dermatitis, limited to mild itching or redness where the resin contacts the skin.

How can I be sure my gauges will fit?

The gauge molds come in mm sizes.  We use electronic calipers to measure the final product in mm and inches.  There is a slight- usually 0.2 to 0.3 inch -difference between our measured diameter and the nearest inch fraction. Here are the exact measurements:

 It can be confusing when some gauges are offered with millimeter(mm) measurements and other with inches.  Here’s how to navigate between them.  

How to use:  Column A is the measured millimeter size.  Column C is the nearest inch size.  

If you usually wear 18mm gauges, what would this be in inches?  Look down Column A for your usual millimeter size.  Slide right along that row to see the nearest inch size in Column C: 11/16. Then look in Column E to find out that the difference between the millimeter size and the inch size is .02”, 2 hundredths of a inch, such a small difference that both sizes will fit you.

Look at column D to see the actual difference in hundredths of a inch between the two sizes.  (Columns B and D contain the mm and inch measurements converted to hundredths of an inch)

A = Millimeters sizes (measured by electronic calipers)

B = Millimeters converted to hundredths of a inch

C = Nearest size in inches

D = Inches converted to hundredths of an inch

E = Difference between mm size and inch size
