Material : Plastic/wood Dimension : 8.5"x 4.5" Refines a child sense of taste Durable and safe for kids Montessori Tasting Bottles are not exactly what most taste buds jump for joy to try out. Still this gustatory work develops and refines a child sense of taste in a remarkable way. The objective of the exercise is to match four fundamental taste types: salty, sweet, bitter and sour. Each bottle in the first set should make a taste pair with a bottle in the second set. Bottle sets can be distinguished by placing labels on them. Brand No Brand SKU 100284732_NP-1020545582
