That’s the problem you’re up against, and this solves it. The printed beer glass is clearly a grandad gift rather than a beer gift, which ties it to that specific relationship instead of being another bit of barware.
The extra pieces turn it into a proper set rather than a single item, so it has some presence when he opens it rather than being one glass in a box.
Because the design names the relationship, it works particularly well coming from grandkids, where the thought behind it matters considerably more than the price.
It also gives younger children something to give that isn’t a drawing or a shop-bought card, which is genuinely useful for parents organising presents on their behalf.
The glass itself is the sort he’ll actually use rather than put on display, which is the right outcome. A novelty item he’s afraid to use isn’t much of a gift.
It covers a lot of occasions, which helps when you’re buying for someone notoriously difficult who insists every year that he doesn’t want anything.
It suits grandads who enjoy a quiet beer and a laugh and appreciate being thought about, which is most of them regardless of what they claim.
Check he still drinks before you buy. It sounds obvious, but health changes in later years are common and not always announced, and a beer glass lands badly if he gave it up six months ago.
