David Holtz
Owner, Designer
Hi, I'm David. I design every ClayMarkStudio stamp myself in my own stamp designer, then make each one by hand to order in Brooklyn. Send me your logo, signature or idea and I'll help turn it into a crisp, clean mark.

Frequently asked questions
Custom and personalized orders
Most of our stamps are made just for you! Order the size you want, choose a shape and style, and type your text. Upload your logo at checkout, on your 3D preview page, or send it to us in a message. After checkout we'll send you a link to see your stamp in 3D, adjust it if you like, and approve it. Nothing custom is made until you approve. Our themed stamp sets are ready-made designs, so they ship without a preview. Have an unusual idea? Message us before ordering and we'll tell you if it will press well.
Care instructions
Rinse your stamp in water after each session and let it air dry. Use a soft toothbrush to clear clay from fine details. Keep it out of hot cars, dishwashers and kilns, since heat can warp it. For the cleanest marks, press into leather-hard clay; a light dusting of cornstarch helps with soft or sticky clay.
Sizing details
Pottery stamps: Small (1" / 25 mm) for initials and simple marks, Medium (1.25" / 32 mm) for most signatures and short names with an icon, Large (1.5" / 38 mm) for full logos and detailed artwork. Themed pottery sets come in Small or Medium. Clay shrinks as it dries and fires, so your fired mark will be a little smaller.
Sprig molds: 1", 1.5" or 2" across the sprig.
Cookie stamps: 2", 2.5" or 3" (cookie stamp sets come in 2" or 2.5"; our holiday family-name stamp in 2.5" or 3"). Pick a size a little smaller than your cookie.
Cookie cutter and stamp sets: 3" or 4", measured on the cutter's longest side.
Soap stamps: 1.5", 2" or 2.5". Match it to your bar's face.
Not sure? Message us your design and we'll recommend a size.
Gift wrapping and packaging
Stamps ship in a padded mailer with no prices inside, so you can send one straight to the potter in your life. Buying a gift but don't know their logo or signature? Order with their name or initials and send the 3D preview link to them to finish the design.
Are your cookie stamps and cutters food safe?
Our cookie stamps and cutters are made from Bambu Lab PLA Pure, a filament that has passed EU food-contact testing (Regulation 10/2011). They're designed for brief contact with dough and fondant. Hand wash in cool, soapy water and dry right away. They're not dishwasher safe and shouldn't go in the oven or touch anything above 140F (60C). Like all printed tools, they have fine layer lines, so clean them well after each use. For extra peace of mind, dust with flour or line with plastic wrap before pressing.
