I always provide measurements in the product's description, in inches and in centimeters. I also include the weight information for most earrings and some necklaces, in grams and ounces. In addition I photograph most items next to a ruler or a coin, to give you a visual clue about the item's size. Please, read the whole description and see all the photos to get a better idea of the item's details. If I left something out, don't hesitate to contact me.

They are certainly pliable, since they are made of wire. Which means they will bend but they will not break. If a wire crocheted item gets squished or deformed in any other way, you can always restore it's shape. Don't be afraid to stretch, squeeze, twist and sculpt them as if they were play-doh. If a tube necklace gets flattened, roll it between your palms and stretch it lengthwise, repeat. Any shape is restorable.

No, but it's not a problem, since the rings are slightly adjustable. It can be tricky for me to crochet a perfectly sized ring, since I do it by hand and there's always human error involved. Even if I use the same number of rows and stitches, the size of the final product will differ slightly every time. Sometimes I even have to re-do the whole ring if I miss the sizing by much (I can't unravel them). But as long as my human error stays within the range of 0.5 ring size, you'll always be able to adjust your ring to your best comfort. Don't forget that the rings are pliable, so you can always stretch or squeeze them slightly. This feature can also come in handy if your fingers tend to swell now and then.

Sorry guys but no. Not even on my hex nut rings.

No, the rings have a standard fit. This can represent a sizing problem for wider bands, like my hex nut rings. You don't have to size up when you place your order, just order your regular ring size and I'll adjust the ring's true sizing to ensure a comfortable fit for your finger.

I offer shipping upgrades and all you have to do is select the right option before you check out. I use USPS services to ship orders and you can always find more details about any specific type of service on USPS website. Within USA: Priority Mail delivery takes 1-3 business days, Priority Mail Express is overnight delivery. For international orders: Priority Mail International takes 6-10 business days, Priority Mail Express International - 3-5 business days. These estimates are taken from USPS website, I'd say they are on the conservative side.
My order processing time is 1-3 business days but if you pay for a shipping upgrade I'll do my best to ship your order on the next business day.
