The ExcelMark Self-Inking DIY Custom Rubber Stamp Kit allows you to create personalized messages for various uses, including address stamps, business information, or teacher stamps. Its self-inking design ensures quick and repetitive stamping, automatically re-inking before each impression. This kit features a two-sided black ink pad, providing double the life by simply flipping it over when the ink starts to fade. With an impression area of 7/8" x 2-5/16", which is larger than many other options, it can accommodate up to five lines of text. The kit includes hundreds of characters and tweezers, making customization easy for all your home or office needs.
