How about a nail art kit or a set of high-quality nail polishes that your husband can use to create his own unique designs? You could also consider booking a nail art class or workshop for him so he can learn new techniques and tips from a professional. Another idea is to commission a custom nail design from a local nail artist or find a nail artist online who can create a custom design for your husband based on his interests or favorite things. This would be a one-of-a-kind gift that he would definitely appreciate.
Or you can get him a star map with the date of your anniversary.
