Kaartoonz’s line testers are brilliant! We use them daily in our traditional animation pipeline, and they’ve drastically improved our workflow. Solid engineering and thoughtful design. Even the punching machine we got works flawlessly — a must-have for any serious 2D setup.

I was skeptical about buying equipment overseas, but Kaartoonz delivered. Their animation lightbox is bright, sturdy, and perfect for hand-drawn work. Shipping took a bit longer than expected, but the product quality made up for it. Will definitely buy the line tester next!

We ordered multiple 2D animation lightboxes from Kaartoonz for our art school, and the build quality is outstanding. The brightness and ergonomics are just right for our students. International shipping was smooth, and their customer support team was always available to guide us. Highly recommended!
