How about getting him a soap carving kit? It could include a set of sculpting tools, various types of soap blocks, and an instruction book or DVD to help him perfect his skills.
Alternatively, you could also book a soap carving workshop for both of you to attend together. This would not only allow him to indulge in his hobby but also create a memorable experience for both of you.
Lastly, if you’re looking for a more sentimental gift, you could create a custom-made soap carving for him. You can have it carved with a specific design or meaningful message, and it would be a one-of-a-kind gift that he can keep for a lifetime.
Or you can get him a star map with the date of your anniversary.
