There is no guarantee your Shellac will be tacky enough to transfer the foils. Foils are designed to work with foil adhesive. For combined shipping/postage just click on "buy it now" for each item you want and "commit to buy" but don't pay for them yet, click on "visit sellers store" and keep returning til you have bought everything you want and when you have finished shopping send me a message and I will send you a combined invoice with the postage discount. If I can help you further please let me know. kind regards Sharon p.s. the ebay app wont allow combined payment, please pay via pc.
