I’m not 100% sure if the cartridges are linked or not, so please assume that they are. Linked means these cartridges are used and have been loaded to either a Cricut Gypsy machine or someone’s online account. However, they can still be used with the older machines that use cartridges (original cricut machine, expression, etc.)Please let me know if you have any questions.Discounts are available if you buy more than 1 cartridge!!!
