Professor Optiken クーポン（選択により価格変動）

I gave this as a birthday gift and my friend loved that she could choose the exact amount herself. The birch wood is surprisingly sturdy and the engraving looks very elegant.

Gave this to my brother for his birthday and he actually kept the wooden card on his desk instead of tossing it like a normal gift card. The engraving looks clean and he wrote his own note on the back with a ballpoint, which worked fine. Redeeming it in the shop was no hassle at all.

I love that I could choose the exact amount—the 100€ option was perfect for my dad, and the birch wood card feels much nicer than a standard plastic gift card.
