Love Letter 💌 Rainbow Bath Bomb – Banana Smoothie Scent
The Love Letter is the show-stopper of the Love Collection — a big, indulgent rainbow bath bomb for kids that’s made to impress.
Shaped like a golden envelope sealed with a red kiss 💋, this brand new design is completely unique to Boddle and has never appeared on the website before. Every detail is hand-painted, giving it that extra-special, keepsake feel before it even hits the bath.
Drop it into warm water and watch as a full rainbow bursts out, creating bold, swirling bath art with layers of colour and plenty of gentle foam. This one looks incredible on video — a proper wow-moment that kids love and mums actually enjoy watching.
Weighing a generous 185g, the Love Letter is one of our bigger bath bombs, making it ideal for gifting or for those baths where you want to go all-out.
Scented in Banana Fruit Smoothie, it smells sweet, creamy and fun — a playful crowd-pleaser that’s especially popular with kids (and secretly nostalgic for grown-ups too).
Originally inspired by one of the very first Boddle Valentine designs, this updated 2026 version has been completely reimagined with richer colours, a brand new shape and bigger bath art.
Perfect as a Valentine’s bath bomb for kids, a Galentine’s treat, or a standout Mother’s Day gift when you want something a bit different from the usual chocolates.
Handmade, joyful and full of colour — because some love letters are better read in the bath. 💖
Maker Info
These bombs were made by me (Jen of Boddle Bath)! I am now a fully assessed bath bomb maker with all the legal PIF files and portal registers that go with it. If you have any questions or bespoke requests please feel free to message me via our social media channels or through the website.
Storage Best Practice
Bath bombs are fickle creatures that do not like sunlight (they tend to fade the colours) or heat and moisture (they get bumpy spots like a rash or go soft and turn to dust) So placing them in a lovely open display dish on the window cill of your bathroom is not a good plan (other than for that insta photo... we see you ;)
Please place your delightful beauties into an airtight container like a takeaway container or the kids lunch box. Then find a spot in the house thats at an even cool temperature, perhaps the back of the wardrobe or understair cupboard. Sprinkling rice or those silica bead sachets you find in new shoes at the bottom of the box is great practice as they will absorb any moisture that might get into the box.
This is majorly important if you select the eco-friendly paper bag option for packaging our bombs instead of shrink wrap. Our bath bombs are assessed for use 12 months after production however I would advice using them within 4-6 months if stored correctly. Outside of shrink wrap that life span will reduce dramatically, to a couple weeks in open air or a month in the container. So please only pick it if you will be using them regularly within the month ideally.
