5X10cm Single Side Copper Prototyping PCB Breadboard 2,5,5,3 Joined Holes (copper proto pcb 5x10cm)
Standard stripboard is great for prototyping and building circuits but it can be time consuming to use with components with certain pin configurations such as IC's. Much time has to be spent breaking tracks to ensure no shorts exist across opposite component pins. This board gets around that problem by having isolated groups of pins.
Solderable PCB breadboards, single-sided PCB, matches breadboards with Power Rails. These boards are especially useful for preserving a prototype or experiment you just created on a solderless breadboard by soldering all the pieces in place.

7 Sizes Colorful Shrinking Tube Kit - 140 pieces (heat shrink colours kit)
Heat-shrink tubing is a shrinkable plastic tube used to insulate wires which provides resistant to abrasion and environmental protection for stranded and solid wire conductors, connections, joints and terminals in electrical work.
Heat-shrink tubes can be used to repair the insulation on wires or to bundle them together, protect wires from minor abrasion, and to create cable entry seals as well as providing environmental sealing protection.
You can use heat gun, or lighter or even oven to heat shrink the tube. Check out this video on example of using Heat Shrink tube.
