Gifts are hard. So if you can't decide, let them choose for themselves!
Kustom Haus Gift Cards can be used to purchase anything in the store including wax seal stamps, sealing wax and accessories. Best of all, gift cards are delivered instantly to your email and contain instructions to redeem them at checkout.
You can then forward your gift card to your recipient or even print it. Gift cards can also be saved in your Apple Wallet on your iPhone. Keep in mind that gift cards are non-refundable but all are valid for 3 years.
