The anniversary of love is exclusive to the two of you. This gift should be related to love and more memorable. I recommend two types: ceramic dolls made from photos. You can use photos of the two of you together, which are more funny and cute, or more romantic and meaningful. Such gifts can serve as a witness to the sweetness of your love. You can also use only your own photos to make it, so that he must see you every day, which also means giving yourself to him, hehe.
Gifts for couples, you can make a couple necklace with your name, or a sterling silver pendant with your name engraved, which are more suitable. This kind of gift is more memorable.
Or if you want to give something practical, you can pay more attention to your boyfriend's life and see what he needs recently. For example, if his wallet is very old and his razor needs to be replaced, you can prepare a new one for him as a gift, which will let him see your careful, considerate and caring side.
