FAQs

Is resin jewelry safe to wear? 

We use ArtResin exclusively 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 completely and 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 has potential for making micro-scratches in the resin surface.  

What do you charge for shipping?

Twelve Houses has a flat rate shipping charge of $3.   If your order totals over $50 (excluding tax and shipping), you’ve earned Free Shipping!!

Do you offer gift wrapping?

Let us know in the notes on the cart page if your item(s) are for gifting.  We'll include a black organza gift bag.

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 among 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.  

Why Twelve Houses?

Zoey and Lu cherish the community of crafters.  There are so many of us, each with different talents, visions and skills.  We view this as an interconnected network of lots and lots of different houses!

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:

Relevant abbreviations and calculations

Mm = millimeters. 

There are 25.4 millimeters in an inch.

Column A:  The actual measurement of the smallest diameter of this double flare gauge.

Column B:  Column A measurement in inches (calculated by dividing measurement A by 25.4 mm per inch.)  Example: 12 mm/25.4mm per inch yields .47 inches)

Column C: Column B measurement rounded to a fraction

Column D:  What column C fraction would be in hundredths of an inch (calculated by top number of column C divided by bottom number of column C)  Example: for the 12 mm row, 1 divided by two is .5 or .50 inches.

Column E:  The difference between column B and column D.
