nothing more than an expensive syringe with tube and cap. I think the sticker on the syringe was probably the most expensive part. The tube was bent and twisted from the way it was packaged, and the tube even broke off once when I put Stans in one of my tires. I think I could get over the fact that it's made out of cheap materials if the price was only $3-$5. I compare it to the quality of a dollar store. Although I love Stan's seal :-)
