PER CURIAM.

       In these consolidated appeals, Theodore T. Browne, who is African-American,
appeals from the final judgment entered in the District Court1 for the Southern District
of Iowa following his guilty plea to conspiring to distribute cocaine base or “crack,”
to possess it with intent to distribute, and to maintain places for the distribution of
cocaine base, all in violation of 21 U.S.C. § 846. Derrick L. Biegler, who also is
African-American, appeals from the district court&s final judgment entered upon his
guilty plea to conspiring to distribute cocaine base or “crack” and to possess it with
intent to distribute, in violation of § 846. In accordance with separate written plea
agreements, the district court sentenced Browne to 210 months imprisonment and four
years supervised release, and Biegler to 136 months imprisonment (reflecting a fifteen-
month credit on a concurrent state sentence) and five years supervised release. In each
case, counsel has filed a brief pursuant to Anders v. California, 386 U.S. 738 (1967),
raising challenges to the sentences imposed. Additionally, Browne has filed two pro
se supplemental briefs and Biegler has filed one. After consideration of the Anders and
pro se briefs, as well as the record, we affirm the judgments of the district court for the
reasons discussed below.

       The Anders brief filed in Browne&s case contains an equal protection challenge
to the 100-to-1 ratio used in establishing the guidelines ranges for crack and powder
cocaine; Browne reiterates the challenge in his pro se briefs. However, Browne may
not challenge the district court&s application of the crack cocaine penalties to him,
because he specifically stipulated in his plea agreement to the 210-month sentence he
received. See United States v. Nguyen, 46 F.3d 781, 783 (8th Cir. 1995) (defendant

who explicitly and voluntarily exposes himself to specific sentence may not challenge
that punishment on appeal). The Anders and pro se briefs also contain various
challenges to the district court&s drug quantity determination. Like the crack penalty
argument, these challenges are foreclosed by Browne&s written plea agreement. We
further conclude that the ineffective assistance claim raised in one of Browne&s pro se
briefs is more appropriately brought in a 28 U.S.C. § 2255 proceeding, where the
matter can first be presented to the district court and the record developed as necessary.
See United States v. Taylor, 82 F.3d 200, 201 (8th Cir. 1996). Finally, we reject
Browne&s contention that he is entitled to have his conviction vacated as a result of
having to prepare his pro se briefs without the full record before him. See Anders v.
California, 386 U.S. at 744 (indigent appellant whose counsel seeks to withdraw must
be furnished with copy of counsel&s brief and given time to raise any points he
chooses).

       In Biegler&s case, both counsel in his Anders brief and Biegler in his pro se brief
challenge the 100-to-1 ratio; Biegler adds that his sentence violates the Eighth
Amendment and suggests he was selected for prosecution based on his race. Biegler
is foreclosed from challenging his sentence because he stipulated to it in his written
plea agreement, see United States v. Nguyen, 46 F.3d at 783, and his claim of
prosecutorial bias is unsupported. Biegler also raises an ineffective assistance claim,
but we conclude once again that such a claim should be raised in a collateral
proceeding.

      Upon review of the record in accordance with Penson v. Ohio, 488 U.S. 75, 80
(1988), we find no nonfrivolous issues. Accordingly, we affirm. We also deny the
remaining pending pro se motions Browne and Biegler filed in this court.
