Does the plaster fail without a meeting?

The plaster will fail if it doesn't open. The longest efficacy of the present plaster is 12 hours! It usually takes about 8 hours to mail. This effect may be strong in the first few hours, but it may not be felt in the next few hours. Don't worry, you will fail slowly. The storage period usually expires after one month. I hope it can be adopted, thank you!
