amazon_item.mpn field not long enough for amazon data on some ASINs

I see this in the db log when I add the asin B0053HSZQG. While the item adds fine and I'm able to see the node (with images etc), but I'm not able to see the item in VIEWS.

Failed to insert item into amazon_item table: Message = SQLSTATE[22001]: String data, right truncated: 1406 Data too long for column 'mpn' at row 1, query= INSERT INTO {amazon_item} (asin, salesrank, detailpageurl, listpriceamount, listpricecurrencycode, listpriceformattedprice, lowestpriceamount, lowestpricecurrencycode, lowestpriceformattedprice, amazonpriceamount, amazonpricecurrencycode, amazonpriceformattedprice, binding, brand, label, manufacturer, mpn, productgroup, producttypename, publisher, studio, title, customerreviews_iframe, timestamp) VALUES (:db_insert_placeholder_0, :db_insert_placeholder_1, :db_insert_placeholder_2, :db_insert_placeholder_3, :db_insert_placeholder_4, :db_insert_placeholder_5, :db_insert_placeholder_6, :db_insert_placeholder_7, :db_insert_placeholder_, :db_insert_placeholder_9, :db_insert_placeholder_10, :db_insert_placeholder_11, :db_insert_placeholder_12, :db_insert_placeholder_13, :db_insert_placeholder_14, :db_insert_placeholder_15, :db_insert_placeholder_16, :db_insert_placeholder_17, :db_insert_placeholder_18, :db_insert_placeholder_19, :db_insert_placeholder_20, :db_insert_placeholder_21, :db_insert_placeholder_22, :db_insert_placeholder_23) fields=
