Really ? Just weapons.
"According to the UN Office for the Coordination of Humanitarian Affairs at various times, Israel has blocked goods including wheelchairs, dry food items, and crayons, Stationery, soccer balls, and musical instruments.International aid group Mercy Corps said it was blocked from sending 90 tons of macaroni and other foodstuffs. After international pressure, Israeli authorities said that they were giving the shipment a green light. Israel was also reported to have prevented aid groups from sending in other items, such as paper, crayons,[citation needed] tomato paste and lentils." The UN have found the blockade to me unlawful from a humanitarian point of view and yet Israel refused to end it.
Israel also forces Palestinians to carry ID cards, sounds all to familiar to me. Because of the blockades families are forced to use Gas bottles for cooking, bought on the black market, there are horrendous injuries weekly to women and children from these cannisters exploding, the victims are then prevented from travelling to specialist burns units because of the blockades, MSF who remain impartial have documented this well.
