How to seal a red envelope with a spike?

Red envelopes are sealed. Use stickers to seal red envelopes. It's good to stick double-sided tape on the sealing sticker.

The other is to take the paste. We used to paste it a long time ago, but now there are double-sided stickers for sale. You can tear off a little to make a red envelope, and the sealing sticker is also very clean and hygienic. I hope my answer can help you. End of answer.
