The placement pen is dipped into wax to help it stick to the diamonds (this is done only when the diamonds stop sticking to the pen). The diamonds are poured into the holder tray, picked up with the placement pen, and placed onto the uncovered area of the sticker. The adhesive on the sticker holds the diamond, releasing it from the pen. The corresponding number on the sticker is covered when the diamond is placed, showing only the sparkling color on top. This process is repeated until all areas of the picture are covered with diamonds.Details:Multicolor Sparkling diamond shades and themed sticker designsResin diamonds, adhesive sticker sheets, plastic toolsSuitable for 8 years and aboveContents:5D diamondsFull drill stickersPoured on adhesivePlacement penWax for the placement penDiamond holder trayTweezersExtra diamond bags
