The word seal indicates security (Matt. 27:66; Eph. 4:30), authentication and approval (John 6:27), certification of genuineness (John 3:33), and identification of ownership (2 Cor. 1:22; Rev. 7:2; 9:4). God is the One who seals, Christ is the sphere in which the seal is done, and the Holy Spirit is the instrument of the seal.The Holy Spirit who seals is a deposit guaranteeing our inheritance. The deposit is more than a pledge which could be returned; it is a down payment with a guarantee of more to come (cf. the firstfruits of the Spirit, Rom. 8:23). A deposit guaranteeing translates the Greek arrabōn (used elsewhere in the NT only in 2 Cor. 1:22; 5:5). It guarantees believers inheritance of salvation and heaven (cf. 1 Peter 1:4). (See comments on inheritance in Eph. 1:18.) In essence, the deposit of the Holy Spirit is a little bit of heaven in believers lives with a guarantee of much more yet to come.
1:14b. The believer is sealed with the Holy Spirit until the redemption (apolytrōsin; of those who are Gods possession. This redemption is not release from the guilt of sin; that was spoken of in Ephesians 1:7 and the believer is already Gods possession. Instead, this is the believers ultimate, final release from the presence of sin (cf. Rom. 8:23b; Phil. 3:2021). The Greek word for possession (peripoiēsis) is also used in 1 Thessalonians 5:9; 2 Thessalonians 2:14; Hebrews 10:39 (see comments there); and 1 Peter 2:9. Again the doxological refrain, to the praise of His glory, is repeated here as it was after the description of the work of the Father (Eph. 1:6) and of the Son (v. 12).

However, the seal is still a mark; it is not a baggie. You may wish to look up signet ring and the wax seal.
Very good.

Agreed; but on the part of the one doing the sealing (God). This is the mark of God put upon individual men. The men may remove that mark - it is not indelible.

Unless the believer rejects that seal at some point, effectively removing it.
