This is a set of two 160ml heat-resistant glass baby bottles. They were used for about 3 months. I mainly breastfed, and used these in rotation with other bottles, so they weren't used very often. Both bottles have all their original accessories. They were sterilized each time after use and stored at home. Although they are made of glass, which is resistant to odors and scratches, they are used items, so there may be some minor scratches or stains from use. Due to shipping costs, I will remove them from the box and fold the box to include it in the shipment. Thank you for your understanding. - Brand: Combi - Model Name: teteo - Material: Heat-resistant glass - Capacity: 160ml - Features: Usable from 0 months - Quantity: Set of 2 We considered the baby's mouth and the breastfeeding mechanism. Babies suck (attach their mouths to the nipple), suckle (tongue movement), and swallow repeatedly during feeding. To allow this repeated action to be performed smoothly, the "4-stage flow adjustment function" unique to Combi is used in the breastfeeding model baby bottle. We are particular about the shape that fits the baby's mouth. The movement of the tongue, the adhesion of the upper lip, the fit to the upper palate... The inside of the mouth is different in shape, top and bottom. After careful consideration, it became an "asymmetrical" shape. And considering the individuality and growth of the mouth, it became "3 sizes". Furthermore, it has "3 nipples" just like a breast. There is also a reason for the design. The "Breastfeeding Model" has a simple and timeless design, and it is designed with the image of a "milk crown". And, considering the milk that is prepared in 20ml and 40ml units, we have added scale numbers. * Sterilization or disinfection by boiling, chemical solution, or microwave is possible. ■ Target age: The target age of the included nipple is from 0 months to about 1.5 months ■ Size: W65 x D63 x H171mm ■ Remarks: Material: Bottle/borosilicate glass, Nipple/silicone As a bonus, there are 5 sheets of NIST odor-proof bags that prevent diaper odors. I have only used one sheet. Thank you for looking.
