3-Piece German-Made Solingen Kitchen Utensils: For Butter/Potatoes/Lemons

This is a set of 3 kitchen gadgets from Solingen, Germany.
I used them at home when I was younger, but they have been stored in the kitchen for nearly 20 years.

① Butter curler... This tool allows you to scoop butter into cute, curly shapes. It's often seen in French restaurants.

② Lemon zester... This tool can peel just the zest from a lemon.

③ Wavy potato baller... With its serrated edge, this tool can scoop out potatoes, creating cute shapes different from regular round scoops.

The set includes the three items listed above.
There is no rust or deformation, but please purchase with the understanding that these are used items.
