These "chop tractors" for beer bottles  are made of large nails. Our logo is printed on the leather patches and there is space on the other side to make your personal engraving.

 They  are available in large quantities, for example to distribute as a promotional gift.
 
 Of course, these graceful stopper pullers are also sold per piece!

 Prefer a stopper puller without a leather loop? See  https://www.arvidcrafts.be/product-page/stoptrekker
