Design your own custom party cups for the big birthday celebration. Made of shatterproof plastic, the 16 oz. stadium-style cups have a level of durability that surpasses other cheap-priced disposable plastic cups. The cups aren't single-use and are reusable, lasting the whole party. The "Happy Birthday" design is versatile. It features a custom photo upload and text personalization on the front and back of the cup. Customize the printed cup for any birthday venue: backyard barbecue, rented halls, beach bonfires, dinner parties, and more. The frosted plastic cup comes in an 8-pack. The upload accepts high-quality photos with a .PNG or .JPEG file extension and high resolution. The image will appear in the preview, where you can adjust its size and placement within the design layout. The final personalization step is adding your own text. On the front, use the text parameters to add the year they were born, or the milestone number of years being celebrated. On the back of the cup, add a name or custom message. Use these characters to thank your guests for attending, write 'Happy Birthday' to the guest of honor, or share a fun sentiment. Because the design uses open text, it works for a first birthday, sweet sixteen, 21st celebration, or an over-the-hill 50th. There are no age limitations. You can also get creative and adapt it to other milestone celebrations like a reunion, anniversary, or graduation.
