VEVOR Cup Heat Press Attachment, 6oz 11oz 12oz 17oz Four Mug Heating Transfer Elements for Heat Press Machine Transfer Sublimation, 110V Silicone Pad Wrap for Mug Coffee Glass Tumbler Cup DIY Printing

Can I use the vevor press attachments for a 20oz skinny tumbler measuring 2.95 diameter by 8" height? If so what attachment do I use?

I am looking for an attachment that will press shot glasses

What machine are these compatible with? I am looking at purchasing the machine "VEVOR Tumbler Heat Press, 30oz Mug Heat Press Machine Sublimation Transfer 11-15oz 16-25oz 30oz Straight Skinny Tumblers, Cup Heat Press with Heat-Resist Gloves & Tape, DIY Ceramic Mugs Cups Glasses" Can i use these on that?

I'm confused.. Is this product only the attachments or the press is included? Please help thanks.
