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.

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.
