I understand that a letter of guarantee is a written document that confirms a person's or an organization's commitment to a specific matter. The following is the general writing template of the guarantee I compiled for your reference:

Title: Letter of Guarantee

Dear [Recipient's Name]:

[Text] Specific Guarantee Matters

Signature: [Your name]

Date: [date of signature]

It should be noted that this template is for your reference only, and the specific content should be modified according to the actual situation.
