This is a holder for drying two sets of sinus rinse bottles. After use, rolling the bottles around to dry them is unsanitary and makes it difficult for them to dry, so I designed this and manufactured it with a 3D printer. It can accommodate both adult and child-sized bottles. If you use the mega size, there is a separate product called Mega Twin. To reduce shipping costs, the screws and legs (made of plastic) will be detached and shipped via regular mail. The screws can be assembled by hand. Please refer to the photos. Delivery may take up to 8 days as it will be sent via regular mail. If you are in a hurry or prefer anonymous shipping, please leave a comment, and I will change it to Nekopos for an additional 100 yen. This allows you to dry and keep your bottles clean for longer use. If you purchase this with other products, I will discount the shipping cost, so please comment. Dimensions: 13cm x 10cm x 3cm Bottles are not included.
