I used this for pressed roses, but I have some left over, so I'm selling it. I will ship via Yu-Packet Plus. ★Remaining amount: 75% (75ml).★ I have used this, but I will also include the plastic cup and brush. The plastic cup has a dent. This is a 100ml product of red flower color developer specifically for pressed flowers. The color developer is only effective for anthocyanin-based red flowers. When used as a reagent, it can determine whether or not a flower contains anthocyanin pigments. It comes with two sheets of synthetic thin paper, a brush, and a 30ml plastic cup. Applicable flowers: Anthocyanin-based red flowers Product use: Maintaining the color of pressed flowers
