PRODUCTION TIME
Production time is 3–5 business days after your design confirmation + shipping.
* IMPORTANT * We’ll send a preview of your personalized design to the email you used for your order—please check your inbox and your spam folder. If we don’t hear back within a few days, we’ll proceed with production as per the preview, unless we have any doubts or are missing a file. You’ll find more shipping details in our Shipping & Returns section.

We produce and ship orders once a week to reduce our environmental impact: delivery drivers only need to come once a week, we can batch orders together, and it helps us stay organized—Biterswit is just the two of us (Carlota and Norma), and we can’t keep up with daily production and shipping. Thanks so much for understanding!

We believe sustainability goes beyond recyclable packaging—our work process aims to be mindful too. So no, your order won’t arrive the next day, but it will arrive lovingly packed by hand, with care and attention to reduce our environmental footprint as much as possible. So all we can say is: thank you for your patience, and for supporting our small studio!

All our stamps are handmade in Barcelona. We cut and mount each one on natural wood from local suppliers.

HOW TO ORDER YOUR CUSTOM STAMP
1. Fill in the Personalization section with the required info. If you need to upload an image, check the format details below.
2. Click the SAVE PERSONALIZATION button so we receive your details. If you don’t click this button, the info won’t be saved and you won’t be able to add the product to your cart.
3. Select your preferred options from the drop-down menus (if needed).
4. Add the product to your cart and complete your purchase.

Once we have all the material we need for your custom order, we’ll send you a digital preview of the design within 24–48 business hours to the email associated with your account. The preview will include the actual size of the stamp design, as this depends on each layout and name.

If you don’t see the email, check your spam folder. If nothing’s there, just write to us at hola@biterswit.com with your order number.

FILE FORMAT FOR IMAGE UPLOAD
If you’re uploading an image, it must be a .JPG file at 300dpi, black and white only (not grayscale), and with a minimum font size of 8pt. We need the largest, highest-quality version you have :) If the file you upload doesn’t meet the quality requirements, we’ll email you as soon as we review your order.

If you have the original Illustrator or a .PDF file, please upload a .JPG during your order and then email the original file to hola@biterswit.com with your order number.
The Illustrator or PDF file must have outlined fonts—meaning all text must be converted to shapes, not editable text. If you're unsure about anything, just send us an email!

I DON’T HAVE MY LOGO OR IMAGE IN BLACK AND WHITE
No worries! If your logo has watercolor textures, shades of gray, or multiple colors, just send us the highest-quality version you have to hola@biterswit.com and we’ll let you know what we can do. There’s always a solution :)

DIGITAL FILE
If you’re purchasing a stamp with a Biterswit design, you can also add the matching digital file to use in your invitations, stationery, signage, guestbooks, websites, videos...
The digital file will be sent as a black-and-white PDF.

In our Stamp Inks section, you’ll find a wide variety of ink colors for different surfaces (we specify the surface type in each product name). Each product includes detailed information and tips to help you get the most out of your ink. We hope this helps!

BITERSWIT GUIDE: STAMP USAGE & CARE
Here’s our Biterswit guide to help you take care of your stamps and inks. Enjoy! ?

HOW TO STAMP? Little tricks :)
1. Start with a little ink. No need to press too hard on the ink pad.
* Sometimes we tend to use too much ink, so it’s best to start with a little bit. Just tap the pad lightly until you get the right amount.
* The amount of ink you need can depend on the surface you're stamping: the more porous and rough the surface, the more ink you'll need.
2. Stamp on a flat surface. Don’t worry if the first impression isn’t perfect — it’s totally normal! New stamps need a little practice. Just have fun and keep testing until you get that perfect print!

WANT TO STAMP ON FABRIC?
If you’re stamping on fabric, go for natural fibers like cotton, linen, and silk. It works great! Just keep in mind that the ink isn’t 100% permanent, so with washing, it’ll fade a bit over time. To make it last longer, just iron the fabric after stamping to really set the ink.
If you want something more durable, we recommend Speedball inks.

STAMP CARE
* Clean your stamps when needed. If you’re using them often and the impressions start getting too ink-heavy, it’s time for a clean! Just don’t scrub too hard or use harsh chemicals.
* Oil-based ink. Inks like Encore are oil-based, and we recommend not overusing them on your stamps because it can damage the material. After using them, clean your stamp by stamping it on paper until it stops leaving marks, and use a cloth or wipe to get rid of any leftover ink. Remember! Never use water to clean stamps with oil-based ink. It reacts with the ink and makes everything sticky (trust us, we know from experience!).
* In addition to the Biterswit guide, we also have a short video where we explain how to store and clean your Biterswit stamps.
